OFF responses

OFF1 and p1300 = 23

Reaction as for OFF2

OFF1, p1501 = "1" signal and p1300 ≠ 23

No separate braking response; the braking response takes place by a drive that specifies the torque.

The pulses are suppressed when the brake application time (p1217) expires. Standstill 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.

Power-on disable is activated.

OFF2

Immediate pulse suppression, the drive coasts to standstill.

The motor brake (if parameterized) is closed immediately.

Power-on disable is activated.

OFF3

Switch to speed-controlled operation

n_set = 0 is input immediately to brake the drive along the OFF3 deceleration ramp (p1135).

When zero speed is detected, the motor brake (if parameterized) is closed.

The pulses are suppressed when the motor brake application time (p1217) has elapsed. Standstill 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.

Power-on disable is activated.
