Ordering data

¹⁾ For the option "Reinforced brake", a brake-version 1FK7 motor must be ordered with B or H in the 15th data position.

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

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

-Z must be added to the Article No. to order a motor with options.

N24
Reinforced brake

When option "Reinforced brake" is selected for S-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 S-1FK7 motors:

• 1FK703.-2....-....
• 1FK704.-2....-.... ; 1FK704.-3....-.... ;
• 1FK706.-2....-.... ; 1FK706.-3....-.... ;
• 1FK708.-2....-.... ; 1FK708.-3....-.... ; 1FK7086-4....-.... ;
• 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 or vapors occur only rarely or briefly in Zone 2 areas. This type of protection is designated as EEx nA II (non sparking).

The special conditions for operating S-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) occurs only rarely or briefly in Zone 22 areas. This type of protection is designated as Ex 3D T 160 °C (320 °F).

The special conditions for operating S-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:
It is not always permissible to combine the option for potentially explosive atmospheres with other motor options. Please refer to the configuration manual for further information.

A version with a DRIVE-CLiQ interface on the motor is only possible for DQI encoders with RJ45 connector. DQ encoders with SMI cannot be combined with option M03 or M39.

N05
Alternative shaft geometry

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

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

Note:
The S-1FK7 motors with the option N05 are always shaft-compatible and flange-compatible with the corresponding S-1FT5 motors.
Exception: S-1FK706 motors are only shaft-compatible with S-1FT506... motors.

N16
Version for increased chemical resistance

Plants and systems in the foodstuff industry or machine tools are typical applications for these types of versions.

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 to 13. Resistance to the acidic and alkaline cleaning products used, as well as disinfectants, was verified by a material resistance test performed by ECOLAB Deutschland GmbH.

Option N16 is available for S-1FK703 to S-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 implemented as 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 for SIMOTICS S-1FT7/S-1FK7 motors with RJ45 connection or with option N16 installed on SINAMICS S120)
