- Description
Siemens 1FK7032-2AK71-1QA0 SIMOTICS S 1FK7-CT servo motor delivers 1.15 Nm standstill torque and 0.5 kW rated power at 6000 rpm on a 600 V DC link. It is a 6-pole design with 1.3 A rated current, IP64 protection, a 20-bit single-turn absolute encoder (AS20DQI) with a DRIVE-CLiQ interface, and no holding brake.

Selection Notes
This is the non-brake version of the 600 V, 6000 rpm 1FK7032-CT variant: without the brake, rotor inertia is 0.650 kgcm² and shaft torsional stiffness is 6,000 Nm/rad, both better than the holding-brake version in the same frame. Pick it for horizontal axes or any application where an external means of holding position already exists - the lower inertia improves dynamic response for high-speed indexing. Against the 300 V / 3000 rpm siblings in this frame, the 600 V DC link here doubles the rated speed to 6000 rpm at a lower 1.3 A rated current.
Applications
1.15 Nm at 6000 rpm without a brake suits high-speed horizontal axes such as pick-and-place heads, rotary indexing, and small conveyor or feed drives where fast settling time matters more than holding torque at standstill.
