Commissioning of torque control mode
1. Set the torque-controlled mode 1300 = 23; p1501 = "1" signal)
2. Enter the torque setpoint using the following parameter:
– p1511: Signal source for supplementary torque 1
– p1512: Signal source for scaling supplementary torque 1.
– p1513: Signal source for supplementary torque 2
3. Issue the enable signals.
OFF responses
● OFF1 and p1300 = 23
– Response as for OFF2
● OFF1, p1501 = "1" signal and p1300 ≠ 23
– No separate braking response; the braking response is provided by a drive that
– The pulses are suppressed when the brake application time (p1217) expires. Standstill
– Switching-on inhibited is activated.
● OFF2
– Immediate pulse suppression, the drive coasts to standstill.
– The motor brake (if parameterized) is closed immediately.
– Switching-on inhibited is activated.

is detected when the actual speed value is less than the speed threshold (p1226) or
when the monitoring time (p1227) that started when speed setpoint ≤ speed threshold
(p1226) has expired.
