The remaining members of CENELEC, Switzerland in particular, also accept the certificates.

Tolerances for electrical data

According to DIN EN 60034, the following tolerances are permitted: Motors which comply with DIN EN 60034-1 must have a voltage tolerance of ?5 % / frequency tolerance of ?2 % (Design A), if utilized, the permitted limit temperature of the temperature class may be exceeded by 10 K.

A tolerance of ?5 % also applies to the rated voltage range in accordance with DIN EN 60034-1.

Efficiency? for
P_N 150 kW: –0.15 ? (1 –?)
P_N >150 kW: –0.1 ? (1 –?)

with? being a decimal number.

• Minimum absolute value: 0.02
• Maximum absolute value: 0.07

Slip ±20 % (for motors <1 kW ±30 % is permissible)
Locked-rotor current +20 %
Locked-rotor torque –15 % to +25 %
Breakdown torque –10 %
Moment of inertia ±10 %

1MA motors:

Add 10 % to the certified values for the locked-rotor current.

Energy-saving motors with European efficiency classification in
accordance with EU/CEMEP (European Commitee of Manufac-
turers of Electrical Machines and Power Electronics)

Low-voltage motors in the output range of 1.1 to 90 kW, 2-pole and 4-pole are marked in accordance with the EU/CEMEP agreement with the efficiency class

(Improved Efficiency) or

(High Efficiency).

So that the requirements of efficiency classes

and

are fulfilled, the active parts of the motor have been optimized. The procedure for calculating the efficiency is based on the loss- summation method according to IEC 60034-2.

Motors for the North American market

For motors which comply with North American regulations (NEMA, CSA, UL, etc.), it must always be checked whether the motors will be used in the US or Canada and whether they are subject to state laws.

Minimum efficiencies required by law

In 1997, an act was passed in the US to define minimum efficiencies for low-voltage three-phase motors (EPACT = Energy Policy Act). An act is in force in Canada that is largely identical, although it is based on different verification methods. The efficiency is verified for these motors for the USA using IEEE 112, Test Method B and for Canada using CSA-C390. Apart from a few exceptions, all low-voltage three-phase motors exported to the USA or Canada must comply with the legal requirements on efficiency.
The law requires minimum efficiencies for 2, 4 and 6-pole motors with a voltage of 230 and 460 V/60 Hz, in the output range of 1 to 200 HP (0.75 to 160 kW). Explosion-proof motors must also be included. 1LA9 and 1LG6 are also available in the design for Zones 2, 21 and 22.
According to EPACT, the following are excluded from the efficiency requirements, for example.

• Motors whose frame size output classification does not correspond with the standard series according to NEMA MG1-12.
• Flange-mounting motors without feet
• Brake motors
• Converter-fed motors
• Motors with design letter C and higher

For more information on EPACT:
http://www.eren.doe.gov/

Special requirements for the USA: Energy Policy Act

The act lays down that the nominal efficiency at full load and a “CC” number (Compliance Certification) must be included on the rating plate. The “CC” number is issued by the US Department of Energy (DOE). The following information is stamped on the rating plate of EPACT motors which must be marked by law: Nominal efficiency (service factor SF 1.15), design letter, code letter, CONT, CC-Nr. CC 032A (Siemens) and NEMA MG1-12.

Special requirements for Canada: CSA – Energy Efficiency Verification

These motors fulfill the minimum efficiency requirements laid down by the CSA standard C390. These motors are available as 1LA9 or 1LG6 and can be ordered with order codeD40and are also marked with the CSA-E verification on the rating plate.

UL approval – Order code D31

The motors based on the 1LA/1LG basic series are listed for up to 600 V by Underwriters Laboratories Inc. (“Recognition Mark” = R/C).
For Zones 2, 21, 22 and EEx e motors or EEx de motors as well as marine motors, there is no listing.
The motors must be ordered with order codeD31, voltage code“9” and the order code for voltage and frequency.
According to UL, motor voltages are only certified up to 600 V, i. e. voltage codes 1, 3, 4 or 5. For this reason, voltage code “6” for example is omitted (400 V?/690 VY/ 50 Hz or 460 V?/60 Hz). Voltages 400 V? and 460 V?, for example, should be ordered as follows:

Voltage	Voltage code
400 V?/50 Hz or 460 V?/60 Hz (50 Hz output)	9 with L1U 1)
460 V?/60 Hz (50 Hz output)	9 with L2T
460 V?/60 Hz (60 Hz output)	9 with L2F

The “UL Recognition Mark” is included on the rating plate of the motor.

In addition, the motor is designed to meet the NEMA MG1-12 electrical standard (with the exception of non-standard motors) and includes the following data on the rating plate: Rated voltage (voltage tolerance of ?10 %), nominal efficiency, design letter, code letter, CONT and NEMA MG1-12.

Externally or internally mounted components such as

• Motor protection
• Heating element
• Separately-driven fan
• Brake
• Encoder
• Power connection
• Plug connector

are UL-R/C, CSA or C-US listed or used by manufacturers in accordance with regulations. It may have to be decided whether the motor is suitable for the application.
The motors can be operated with a frequency converter – separate converter or built-on (1UA7/order codeH15) – with 50/60 Hz.
Deviating frequency settings must be tested at final acceptance.

The external fans for 1LA8 and 1LL8 motors must be made of metal.

The following versions are possible:

• 2-pole 2) motors, only in combination with K37 or K38
• 4, 6 and 8-pole motors, only in combination with K35

For 1PQ8 motors, UL listed motors with separately-driven fan (400 VD 50 Hz/460 VD 60 Hz) are used. Other voltages up to 600 V and/or other frequencies must be ordered using the order code Y81 and plain text. For 1LA8 and 1PQ8 motors of frame size 315, when option D31 is ordered, connection box gt 640 will be automatically replaced at no extra charge with connection box 1XB1 621. The connection boxes are designed with an undrilled cable entry. UL-R/C cable glands must be used for cable entry.

CSA approval – Order code D40

Motors based on the 1LA/1LG basic series are approved for up to 690 V in accordance with the Canadian regulations of the
“Canadian Standard Association” (CSA). Externally or internally mounted components which are used are listed by CSA or are used by manufacturers in accordance with regulations. It may have to be decided whether the motor is suitable for the application. For Zones 2, 21, 22 and EEx e motors or EEx de motors as well as marine motors, there is no approval.

The motors must be ordered with the order codeD40, voltage code“9” and order code for voltage and frequency. The CSA 10 %) are included on the?mark and the rated voltage (voltage tolerance of rating plate.

When energy-saving motors (1LA9, 1LG6) are ordered, they also include the CSA-E mark on the rating plate.

Other versions:

For versions and certification of explosion-proof motors in compliance with directive 94/9/EU (ATEX) as well as VIK versions, see Section 4 “Explosion-proof motors”.
For versions for use in shipping, see Section 10 “Marine motors”.

Test certificates

Acceptance test certificate 3.1 according to EN 10204 – Order codeB02

An acceptance test certificate 3.1 according to EN 10204 can be supplied for most motors.

The tests listed below are mainly intended for non-standard motors (Part 3). The assignment of order codes to motor types can be found in the “Special versions” section of the relevant catalogue sections.

Standard test (routine test) with acceptance – Order codeF01

Standard routine testing of the motor, but with acceptance by an external representative (e.g. customer). The routine test is required to check the correct functioning of a motor where the characteristic data are known and were determined on a machine of the same type in a detailed type test. For a routine test, characteristic variables are determined, which after being converted to the basic data, are compared with the reference values for this machine type.

Visual acceptance and report handover with acceptance – Order codeF03

Visual acceptance of the motor by an external representative (e.g. customer) and handover of the routine test report to the external representative (e.g. customer).

Temperature-rise test without acceptance – Order codeF04

For the temperature-rise test, the temperature rise of a motor is measured in continuous duty. To do this, the motor is connected to a load (dynamometer), and operated with the rated power.

Temperature-rise test with acceptance – Order codeF05

As for order code F04, but with acceptance by an external representative (e.g. customer).

Noise measurement during idling, no noise analysis, no acceptance – Order codeF28

The A-rated sound pressure level L_pA is measured during idling at rated voltage. The number of measuring points and their locations are specified in the test certificate.

Noise measurement during idling, no noise analysis, with acceptance – Order codeF29

As for order code F28, but with acceptance by an external representative (e.g. customer).

Recording of current and torque curves with torque metering shaft during starting, without acceptance – Order code F34

The measurement is used to determine the starting response of a motor. By comparison with the load torque characteristic, the acceleration torque can be calculated. This can be used to check that a complete machine set has started correctly.
This measurement is only meaningful for motors that are directly line-fed and is not offered for motors that are designed for converter-fed operation.

Recording of current and torque curves with torque metering shaft during starting, with acceptance – Order codeF35

As for order code F34, but with acceptance by an external representative (e.g. customer).

Measurement of the locked-rotor torque and locked-rotor current without acceptance – Order codeF52

The torque and current are determined when the rotor is locked. This measurement is only meaningful for motors that are directly line-fed and is not offered for motors that are designed for converter-fed operation.

Measurement of the locked-rotor torque and locked-rotor current with acceptance – Order codeF53

As for order code F52, but with acceptance by an external representative (e.g. customer).

Noise measurement during idling, with noise analysis, without acceptance – Order codeF62

As for F28, but a noise analysis is also performed. The signal is divided up into frequency bands and the level is determined in each band.

Noise measurement during idling, with noise analysis, with acceptance – Order codeF63

As for order code F62, but with acceptance by an external representative (e.g. customer).

Type test with heat run for horizontal motors, without acceptance – Order codeF82

During the type test, a temperature-rise test is performed; no- load, short-circuit and load characteristics are recorded; the iron losses and friction losses are determined and the efficiency is calculated from the summed losses. This option is only applicable to motors with a horizontal type of construction.

Type test with heat run for horizontal motors, with acceptance – Order codeF83

As for order code F82, but with acceptance by an external representative (e.g. customer, classification society).

Type test with heat run for vertical motors, without acceptance – Order codeF92

As for order code F82, but only for motors with a vertical type of construction.

Type test with heat run for vertical motors, with acceptance – Order codeF93

As for order code F92, but with acceptance by an external representative (e.g. customer, classification society).

Voltages, currents, frequences

EN 60034-1 differentiates between Category A (combination of voltage deviation +5 % and frequency deviation +2 %) and Category B (combination of voltage deviation +10 % and frequency deviation +3/–5 %) for voltage and frequency fluctuations. The motors can supply their rated torque in both Category A and Category B. In Category A, the temperature rise is approx. 10 K higher than during normal operation.

The rated currents at 420 V and for 1LA8/1PQ8/1LL8 motors 660 V or 725 V are listed in the table on Pages 1/25, 1/26 and on the rating plate.

The tolerance laid down by DIN EN 60034-1 applies to all converter-fed 1LA8 motors as well as to 1LA5, 1LA7, 1LG6, 1PQ8 and 1LL8 motors with special 690 V insulation, i.e. no rated voltage range is specified on the rating plate.

For 1LA and 1LG motors, type of protection “n” (Zone 2), a rated voltage range is not specified.

¹⁾ Only available for 680 V see chapter 3 “Non-standard motors frame size 315 and above”.

²⁾ Only available for 725 V see chapter 3 “Non-standard motors frame size 315 and above”.

The rating plates of 1MJ6 motors specify the maximum current in the voltage range in addition to the rated current.
This maximum is approximately 5 % higher than the rated current.

Outputs

The outputs and the rated outputs are listed in the selection tables and in the separate catalog sections for 50 Hz and in most cases also for 60 Hz. For 60 Hz, the rated output values must, in some cases, be increased, e.g. for pole-changing motors.

Rated torque

The rated torque in Nm delivered at the motor shaft is

P  Rated output in kW

n  Speed in rpm

Note:

If the voltage deviates from its rated value within the allowed limits, the locked-rotor torque, the pull-up torque and the breakdown torque vary with the approximate square of the value, but the locked-rotor current varies approximately linearly.

In the case of squirrel-cage motors, the locked-rotor torque and breakdown torque are listed in the selection tables as multiples of the rated torque.
The normal practise is to start squirrel-cage motors directly on line. The torque class indicates that with direct-on-line starting, even if there is - 5 % undervoltage, it is possible to start up the motor against a load torque of

• 160 % for KL 16
• 130 % for KL 13
• 100 % for KL 10
• 70 % for KL 7
• 50 % for KL 5

of the rated torque.

The individual torque characteristics are available in the SD configurator. In addition, it is possible to perform calculations with the supplied start-up program.

For type 1MA motors in the standard design for T1/T2 and T3 and different rated outputs, the torque class specified for the higher output applies.

Rated speed and direction of rotation

The rated speeds are applicable for the rated data. The synchronous speed changes proportionally with the line frequency.
The motors are suitable for clockwise and counter-clockwise rotation.

This does not apply to the following 2-pole motors:

• 1LA8, 1LL8 frame size 355 and above for clockwise rotation only; alternatively order codeK38 for counter-clockwise rotation only
• 1LA8, 1MJ8, 1MJ6, 1MJ1, 1MA6 and 1LG4 in VIK version from frame size 315 and above.

If U1, V1, W1 are connected to L1, L2, L3, clockwise rotation results as viewed onto the drive-end shaft extension. Counter- clockwise rotation is achieved by swapping two phases (see also “Heating and ventilation”).

Rating plate and extra rating plate

DIN EN 60034-1 lays down that the approximate total weight for all motors from frame size 90 (from approx. 30 kg) is indicated on the rating plate.

An extra rating plate can be supplied loose for all motors, order codeK31.
Supplementary data can be indicated on the rating plate and on the packaging label, order codeY84.

An extra rating plate can also be supplied for the customer's data, order codeY82.
An extra rating plate or a rating plate can also be ordered with different rating plate data, order codeY80.

In the standard version, the rating plate is available in international format or in the English/German language. The language for the rating plate can be ordered by specifying in plain text. An overview of the languages that can be ordered, at additional cost in some cases, is provided by the table below.

In addition, for 1MA motors:
With the exception of 2-pole motors from frame size 225 M or larger, all motors are suitable for both T1/T2 and T3 (uniform design).
If the rated output for T1/T2 differs from that of T3, the data for both output values is stated separately.

Example of rating plates

See the section of the catalog “Non-standard motors” for rating plates for motor series 1LA8, 1PQ8 and 1LL8

Ambient temperature and site altitude

The rated output specified in the selection tables is applicable for continuous duty in accordance with DIN EN 60034-1 at a frequency of 50 Hz, a coolant temperature or ambient temperature (AT) of 40 °C and a site altitude (SA) or up to 1000 m above sea level.

For higher ambient temperatures and/or site altitudes higher than 1000 m above sea level, the specified motor output must be reduced using the factor k_HT.

Depending on the frame size of the motor or the number of poles, special windings may be added to the motors for the different operating conditions.

This results in a maximum output of the motor of:

P _zul =P_N · k_HT

If the maximum motor output is no longer adequate for the drive, it should be checked whether the motor with the next higher rate output fulfills the requirements.

Abbreviation	Description	Units
P max.	Maximum motor output	kW
P rated	Rated output	kW
kHT	Factor for abnormal ambient temperature and/or site altitude

The motors are designed for temperature class F and used in temperature class B. Under non-standard operating conditions, if they are to be used in class B, the maximum output must be determined from the tables below.
If explosion-proof motors are to be used (with the exception of 1MJ6) at ambient temperatures that exceed 40 °C and site altitudes higher than 1000 m above sea level, the appropriate correction factors must be requested.

Restarting against residual field and opposite phase

All motors can be reclosed against 100 % residual field after a line voltage failure.

Motor protection

A distinction is made between current-dependent and motor- temperature-dependent protection devices.

Current-dependent protection devices

Fusesare only used to protect mains cables in the event of a short-circuit. They are not suitable for overload protection of the motor.

The motors are usually protected by delayed overload protection devices (circuit breakers for motor protection or overload relays). This protection is current-dependent and is particularly effective in the case of a locked rotor.

For standard duty with short start-up times and starting currents that are not excessive and for low numbers of switching operations, motor protection switches provide adequate protection. Motor protection switches are not suitable for high starting duty or large numbers of switching operations. Differences in the thermal time constants for the protection equipment and the motor results in unnecessary early tripping when the protection switch is set to rated current.

Protection devices that are motor temperature sensitive

Temperature monitorsinstalled in the motor winding are suitable protection devices in the case of slowly rising motor temperature.

When a limit temperature is reached, thesebimetal switches(NC contacts) can deactivate an auxiliary circuit. The circuit can only be reclosed following a considerable fall in temperature. When the motor current rises quickly (e.g. with a locked rotor), these switches are not suitable due to their large thermal time constants.
3 temperature detectors for tripping
Order codeA31

The most comprehensive protection against thermal overloading of the motor is provided byPTC thermistors(thermistor motor protection) installed in the motor winding. Due to its low heating capacity and excellent thermal contact with the winding, the winding temperature can be closely monitored.
When a limit temperature is reached (nominal tripping temperature), the PTC thermistor undergoes a step change in resistance. This is evaluated by a tripping unit and can be used to open auxiliary circuits. The PTC thermistors themselves cannot be subjected to high currents and voltages. This would result in destruction of the semiconductor. The switching hysteresis of the PTC thermistor and tripping unit is low, which supports fast restarting of the drive. Motors with this type of protection are recommended for high duty starting, switching duty, extreme changes in load, high ambient temperatures or fluctuating supply systems.

Motor protection with PTC thermistors with 3 embedded temperature sensors for tripping.
In the connection box, 2 auxiliary terminals are required. The maximum number of auxiliary terminals in the main connection box of the motor is specified under “Number of auxiliary terminals” in the section “Motor connection and connection boxes”. An auxiliary connection box is required when the total number of auxiliary terminals in the connection box of the motor exceeds the specified values. For an additional charge, the connections can be routed through a separate auxiliary connection box (order code L97, M50 or M88, see “Auxiliary connection box”
in the section “Motor connection and connection boxes”).
Order codeA11

For pole-changing motors with two separate windings, the number of temperature sensors must be doubled.

Two sets of three temperature sensors are used if a warning is required before the motor is shut down (tripped). The warning is normally set to 10 K below the tripping temperature.

• All 1LA8 motors are equipped in the standard version with 6 PTC thermistors for alarm and tripping.
• For 1LA, 1MJ and 1LG motors, the tripping temperature corresponds to PTC thermistors for temperature class F.
• For 1LA8, 1LL and 1PQ motors, the tripping temperature corresponds to PTC thermistors for temperature class F, also for 1LA8 in Zone 22.
• For 1LA and 1LG motors for Zones 2, 21, 22 or VIK thermistors temperature class B for Zone 2 and VIK (see catalogue section “Motors operating with frequency converters”).

In order to achieve full thermal protection it is necessary to combine a thermally delayed overcurrent release and a PTC thermistor. For full motor protection implemented only with PTC thermistors, please enquire.

Motors whose windings are at risk of condensation due to the climatic conditions, e.g. inactive motors in humid atmospheres or motors that are subjected to widely fluctuating temperatures can be equipped with anti-condensation heaters.
An additional cable entry M16 x 1.5 or M20 x 1.5 (M20 x 1.5 or M25 x 1.5 for 1LA8, 1PQ8 and 1LL8 motor series) is provided for the connecting cable.
Anti-condensation heaters must not be switched on during operation.

1MJ6 motors:
For 1MJ6 motors up to frame size 160 L, a built-in anti-condensation heater is not possible for versions with PTC thermistors.

For 1MA and 1LA motors In designs for Zone 21:
Built-in anti-condensation heaters are not possible up to frame size 200L.

For 1LA. motors in designs for Zones 2 and 22:
Built-in anti-condensation heaters are available on request.

For 1LA8 and 1PQ8 motor series in designs for Zone 2, the anti- condensation heater can only be switched on after the motor has been switched off for one hour.

Instead of an anti-condensation heater, another possibility (at no extra cost) is connection of a voltage that is approximately 4 to 10 % of the rated motor voltage to stator terminals U1 and V1; 20 to 30 % of rated motor current is sufficient to heat the motor (this does not apply to 1MA6 frame sizes 225 M to 315 L, 1LA8, 1PQ8 and 1LL8).

Fans/Separately-driven fans

Motors of frame sizes 63 to 450 have radial-flow fans in the standard version that cool regardless of the direction of rotation of the motor (cooling method IC 411 acc. to DIN EN 60034-6, IC01 for 1LL8 motor series). The air flow is forced from the non-drive-end (NDE) to the drive end (DE). Motors of frame size 56 do not have a fan (IC 410). For details of seperately-driven fans for frame sizes 100 to 315, see also Page1/75.

1MJ1 and 1MJ8 (frame size 355) 2-pole and 4-pole motors have an axial-flow fan for clockwise rotation in the standard version. The fan can be subsequently reinstalled for anti-clockwise rotation. Exception: 1MJ1 motors, frame size 450, 2-pole.

1LA8 and 1LL8 (frame size 355) 2-pole motors have an axial- flow fan for clockwise rotation in the standard version. The fan can be subsequently reinstalled for anti-clockwise rotation. Motors of the 1LA8 series are also available in a version with a separately driven fan (cooling method IC 416 – 1PQ8 series) and in a version with through-ventilation (cooling method IC 01, IP23 degree of protection – 1LL8 series). 1PQ8 motors have separately-driven fans that cool regardless of the speed of the main motor (IC416).

Line voltages for 1PQ8 separately-driven fans:
230 V?/400 VY ±10 %, 50 Hz, 460 V? ±10 %, 60 Hz.
Other voltages/frequencies can be ordered by specifying in plain text with order codeY81(price supplement).

Line voltage of separately-driven fan for 1LG motors:
The line voltage of the 1PP9 motors with separately-driven fan is adapted for voltages outside the rated voltage range to the voltage of the 1LG motor.
The line voltage tolerance for the separately-driven fan is ±10 %.

When the motor is mounted and the air intake is restricted, then it must be ensured that a minimum clearance is maintained between the fan cover and the wall. This clearance is calculated from the difference between the protective cover and the fan cover (dimension LM - L) or is specified in the detail dimension drawing.

For design of the fan/separately-driven fan and the fan cover, see the tables below.
