KUKA 1FK7100-5AZ91-1ZZ9-Z & 1FK7103-5AZ91-1ZZ9-Z Synchronous Servo Motor | 1FK7 Series Platform
Engineering Background
The KUKA 1FK7 series synchronous servo motors are engineered for high-dynamic, precision motion control in industrial automation. Developed on the Siemens SIMOTICS S platform and integrated into KUKA robotic and CNC drive systems, these motors deliver exceptional torque density, thermal stability, and encoder accuracy. Part numbers 1FK7100-5AZ91-1ZZ9-Z (KUKA PN: 00-117-606 / 00-122-284C2ksd1-08) and 1FK7103-5AZ91-1ZZ9-Z (KUKA PN: 00-119-768) represent the upper-mid power range of the 1FK7 family, widely deployed in KUKA KR series robot axes and precision machine tool spindle drives.
Product Positioning
These motors are the preferred choice for procurement engineers sourcing replacement or upgrade drives for KUKA robotic cells, servo press lines, and multi-axis CNC machining centers. Konmask.com supplies verified OEM units with full traceability, supporting both MRO replacement and new system integration projects.

Engineering Advantages
- High Torque Density — Compact frame delivers 3.2 kW and 5.9 kW respectively with minimal footprint
- DRIVE-CLiQ Interface — Plug-and-play encoder communication with SINAMICS S120 and KUKA KRC4 controllers; eliminates manual encoder parameterization
- Absolute Multiturn Encoder — Retains position reference through power cycles; no homing routine required after restart
- Thermal Stability — Class F insulation and optimized winding geometry sustain rated output in continuous duty cycles
- Low Cogging Torque — Smooth velocity control at low speeds; critical for precision contouring and force-sensitive applications
- Standardized Mounting — IEC flange dimensions ensure drop-in compatibility with existing machine frames
System Architecture & Signal Flow
In a typical KUKA KRC4 robotic cell, the 1FK7 servo motor connects to the KUKA servo drive module via a DRIVE-CLiQ encoder cable and a power cable. The KRC4 controller issues position/velocity/torque setpoints over the internal EtherCAT bus to the drive module, which executes closed-loop current control at the motor. The absolute encoder feeds back actual position data at 4096 counts/revolution (multiturn: 4096 revolutions), enabling sub-arc-minute positioning accuracy. For SINAMICS S120 standalone configurations, the motor integrates directly into the booksize or chassis drive topology with identical wiring conventions.

Technical FAQ
Q: Are these motors compatible with SINAMICS S120 drives outside of KUKA systems?
A: Yes. The 1FK7 series is a Siemens motor platform. When used with SINAMICS S120, standard motor data sets (MDS) are available in STARTER/SCOUT software for seamless commissioning.
Q: What is the difference between 1FK7100 and 1FK7103?
A: The 1FK7103 is a longer stack length variant of the same frame size, delivering higher rated torque (5.9 kW vs 3.2 kW) while maintaining identical flange and shaft dimensions — enabling direct mechanical substitution where higher power is required.
Q: Can I use these motors as direct replacements without re-parameterizing the drive?
A: Yes, provided the replacement motor carries the same part number. The DRIVE-CLiQ encoder stores motor nameplate data electronically; the drive reads it automatically on first power-up.
Q: What encoder cable length is supported?
A: DRIVE-CLiQ encoder cables are supported up to 100 m (standard shielded cable). For longer runs, consult Siemens cable extension guidelines.
Q: Do you provide installation and commissioning support?
A: Konmask provides remote technical guidance via email and video call. On-site commissioning services can be arranged through our partner network in major industrial regions.
