– n_set = 0 is input immediately to brake the drive along the deceleration ramp (p1121).
– When zero speed is detected, the motor holding brake (if parameterized) is closed
(p1215). The pulses are suppressed when the brake application time (p1217) expires.
Zero speed is detected when the actual speed drops below the speed threshold
(p1226) or once the monitoring time (p1227) started when speed setpoint ≤ speed
threshold (p1226) has expired.
– Immediate pulse suppression, the drive coasts to a standstill.
– The motor holding brake (if parameterized) is closed immediately.
– Switching on inhibited is activated.
– n_set = 0 is input immediately to brake the drive along the OFF3 deceleration ramp
(p1135).
– When zero speed is detected, the motor holding brake (if parameterized) is closed.
The pulses are suppressed when the brake application time (p1217) expires. Zero
speed is detected when the actual speed drops below the speed threshold (p1226) or
once the monitoring time (p1227) started when speed setpoint ≤ speed threshold
(p1226) has expired.
– Switching on inhibited is activated.
