Ordering data

¹⁾ For the paint finish, 1FK702 motors must be ordered with 3 or 5 in the 16th data position.

²⁾ For primer, 1FK702 motors must be ordered with 0 or 2 in the 16th data position.

When ordering a motor with options, -Z must be added to the article number.

N24
Reinforced brake

When option "Reinforced brake" is selected for 1FK7 motors, they are fitted with a holding brake that is stronger than the standard brake (cf. built-in holding brakes).

The option "Reinforced brake" is available for the following 1FK7 motors:

• 1FK703.-2....-....
• 1FK704.-2....-....
• 1FK704.-3....-....
• 1FK706.-2....-....
• 1FK706.-3....-....
• 1FK708.-2....-....
• 1FK708.-3....-....
• 1FK7101-2....-....
• 1FK7101-3....-....
• 1FK7103-2....-....
• 1FK7103-3....-....
• 1FK7105-2....-....
• 1FK7105-3....-....

Note:
Check whether the mechanical components of the customer's machine are capable of withstanding increased forces and torques in the event of an Emergency Off scenario before using motors with a reinforced brake.

M03
Version for potentially explosive atmospheres Zone 2
in accordance with IEC EN 60079-15

Combustible or potentially explosive gases and vapors develop only rarely or for brief periods in Zone 2 areas. This type of protection is designated as EEx nA II (non sparking).

The special conditions for operating 1FK7 motors in Zone 2 areas, in particular the reduction in permissible operating speeds, are described in detail in Annex 610.40089.01 to the EC Declaration of Conformity 664.20038.02.

M39
Version for potentially explosive atmospheres Zone 22
in accordance with IEC EN 61241-1

Combustible or potentially explosive dust (non-conductive dust) develops only rarely and for brief periods in Zone 22 areas. This type of protection is designated as Ex 3D T 160 °C (320 °F).

The special conditions for operating 1FK7 motors in Zone 22 areas are described in detail in Annex 610.40090.01 to the EC Declaration of Conformity 664.20039.02.

Note regarding options M03 and M39:

When used in Zone 2 or Zone 22, 1FK7 motors are only designed for encoder connection through connectors. A version with a DRIVE-CLiQ interface on the motor is possible only for DQI encoders with RJ45 connector. DQ encoders with SMI cannot be combined with option M03 or option M39. Connection to SINAMICS S120 is only possible via SMC (Sensor Module Cabinet-Mounted).

N05
Alternative shaft geometry

1FK7 motors are delivered with a shaft extension that has an alternative shaft geometry (smaller dimensions).

• 1FK703: 11 ? 23 mm (0.43 ? 0.91 in)
• 1FK704: 14 ? 30 mm (0.55 ? 1.18 in)
• 1FK706: 19 ? 40 mm (0.75 ? 1.57 in)
• 1FK708: 24 ? 50 mm (0.94 ? 1.97 in)
• 1FK710: 32 ? 58 mm (1.26 ? 2.28 in)

Note:
The shaft and flanges of 1FK7 motors with option N05 are always compatible with the corresponding 1FT5 motors.
Exception: The shaft of 1FK706... motors is only compatible with 1FT506... motors.

N16
Version for increased chemical resistance

1FK7 motors with option N16 are designed for operation in food processing environments.

The PS Premium paint system of these motors is resistant to a broad range of commonly used cleaning agents and disinfectants.

Additional properties of motors equipped with option N16:

• 4-coat paint system
• Nickel-plated connector

Note:
The PS Premium paint system has been tested with a broad spectrum of industrial cleaning products with pH values ranging from 1.5 – 13. Resistance to the acidic and alkaline cleaning agents and disinfectants in general use was verified in a material resistance test conducted by the company ECOLAB Deutschland GmbH.

Option N16 is available for 1FK703 to 1FK710 motors with the following encoders:

• AM20DQI (1FK7...-.....-.R..)
  Absolute encoder 20 bit + 12 bit multi-turn with DRIVE-CLiQ interface
• AM24DQI (1FK7...-.....-.C..)
  Absolute encoder 24 bit + 12 bit multi-turn with DRIVE-CLiQ interface
• AS24DQI (1FK7...-.....-.B..)
  Absolute encoder, single-turn, 24 bit with DRIVE-CLiQ interface
• AM2048S/R (1FK7...-.....-.E..)
  Absolute encoder 2048 S/R, 4096 revolutions, multi-turn, with EnDat interface
• Multi-pole resolver (1FK7...-.....-.S..)
• Two-pole resolver (1FK7...-.....-.T..)

Motors with DRIVE-CLiQ interface differ from the standard motor version in the following respects:

• The motor is 5 mm longer and has the same overall length as a motor without DRIVE-CLiQ interface.
• The connector is a rotatable angle plug.
• The height of the interfering contour relative to the motor center is 82 mm (3.23 in)
• A non-standard signal cable is required (see MOTION-CONNECT connection systems > Connection overview of SIMOTICS S-1FT7/-1FK7 motors with RJ45 connection or with option N16 installed on SINAMICS S120)
