1FK7042-5AF71-1AA0 — Siemens SIMOTICS S-1FK7 High-Dynamic Servo Motor
The Siemens SIMOTICS S-1FK7 is a permanent magnet synchronous servo motor purpose-built for the SINAMICS S120 and S210 drive systems, delivering high torque density and superior dynamic performance for demanding machine tool, robotics, and precision positioning applications. The 1FK7 range covers rated torques from 0.9 Nm to 34 Nm across eight frame sizes with rated speeds of 3000 to 6000 rpm, and the innovative DRIVE-CLiQ digital interface on every motor transmits full motor identification data, encoder values, and thermal monitoring directly to the S120 drive over a single cable — eliminating the need for separate encoder and motor data configuration at commissioning.
The motor's sinusoidal encoder with 2048 pulses per revolution and optional absolute multi-turn encoder (4096 revolutions) supports both high-speed continuous operation and absolute position tasks such as homing-free return-to-reference in machine tools after power cycles. The integrated optional holding brake, available in three torque sizes, prevents axis drop in vertical axis configurations typical of machining centres and gantry robots. The 1FK7's thermal design uses Class F insulation rated to 155°C and IP64 sealing as standard, with IP65 available as an option for coolant-splash environments common in machine tool applications in Saudi Arabia's metalworking and manufacturing sector.
The SIMOTICS S-1FK7 is deployed across Saudi Arabia's precision manufacturing and defence industrial base, with installations at the Saudi Aramco Upstream Engineering workshops, GAMI-supported defence manufacturing facilities in Riyadh, and the advanced manufacturing centres being established under Vision 2030's industrial diversification programme. The motor's compatibility with the SINAMICS S120 booksize drive system allows multi-axis machine configurations of up to 16 axes on a common DC bus, making it the go-to servo motor for Saudi Arabia's growing CNC machining and robotic welding sectors.
Razz Middle East supplies SIMOTICS S-1FK7 motors as part of complete SINAMICS S120 drive system packages, including power modules, control units, and DRIVE-CLiQ cables. We provide application engineering support for axis sizing, thermal analysis, and TIA Portal project integration.

Key Features & Benefits
- DRIVE-CLiQ single-cable interface transmits motor nameplate data, encoder feedback, and winding temperature monitoring to the S120 drive over one cable, eliminating separate encoder wiring and automatic commissioning errors.
- Absolute multi-turn encoder option (4096 rev × 2048 ppr) provides homing-free position reference after power cycles, reducing machine restart time in machining centres from minutes to seconds.
- High torque density achieved through neodymium rare-earth magnet technology delivers rated torque in a frame size 30–40% smaller than comparable induction servo motors, enabling more compact machine designs.
- Optional integrated holding brake prevents vertical axis drop when drive is de-energised — essential for machining centre Z-axes and gantry robot vertical joints where workpiece safety is critical.
- IP64 sealing as standard (IP65 option) protects motor winding and bearing from coolant splash in machine tool environments, extending mean time between failures in the coolant-rich conditions of Saudi precision machining facilities.
- Class F insulation (155°C) supports continuous operation in high-ambient industrial environments and allows 50% overload for 60 seconds, accommodating the torque spikes of high-acceleration packaging and robotics axes.
- Eight frame sizes with consistent flange and shaft dimensions across the range allow drive system designers to scale axis power without redesigning machine mechanical interfaces — a key advantage for Saudi OEM machine builders.
Industrial Applications in Saudi Arabia
- CNC machining centre X, Y, and Z axis drives at precision component manufacturers serving Saudi Aramco and SABIC engineering workshops, where absolute encoder position retention eliminates homing cycles after tool changes.
- Industrial robot joint actuators for 6-axis welding and material handling robots at automotive and defence manufacturing facilities in Saudi Arabia's industrial cities, where 34 Nm motors drive the heavy wrist joints.
- Printing machine registration and impression cylinder drives at commercial printing facilities in Riyadh and Jeddah, where DRIVE-CLiQ enables sub-microsecond synchronisation between web tension and register control axes.
- Injection moulding machine clamp and injection axes for plastics manufacturers in MODON industrial estates, where the 1FK7's dynamic response reduces cycle time and improves shot-weight consistency.
- Semiconductor and electronics assembly equipment axes at Saudi technology manufacturing facilities under Vision 2030, where the absolute encoder provides the micrometre-level positioning accuracy required for PCB drilling.
- Textile warp beam drive and let-off axes on weaving machines at Saudi textile manufacturers, where constant tension control across the full beam diameter range maintains fabric quality throughout production runs.
- Pharmaceutical tablet press and capsule filling machine axes, where the holding brake prevents contamination from axis creep during STO safety stop events and the IP64 sealing withstands cleaning agent wash-down.
