Selection Notes

This QA0 variant has no holding brake, so on a vertical or overhung-load axis the servo drive or an external brake must hold position when power is removed; where the axis must stay parked without drive power, the version with an integrated holding brake in the same frame is the correct choice. At 36 Nm standstill torque and 2000 rpm nominal speed with an 8-pole winding, this motor suits indexing and pick-and-place axes that need moderate torque rather than the higher continuous power of a larger frame size in this series. The 20-bit single-turn Drive-CLiQ encoder (AS20DQI) gives absolute position feedback without a separate battery-backed multi-turn module.
