– Immediate pulse suppression, the drive coasts to standstill.
– The motor brake (if parameterized) is closed immediately.
– Switching on inhibited is activated.
– Switch to speed-controlled operation
– n_set = 0 is input immediately to brake the drive along the OFF3 deceleration ramp
(p1135).
– When standstill is detected, the motor brake (if parameterized) is closed.
– The pulses are inhibited when the motor brake closing time (p1217) has elapsed.
Standstill is detected when the speed actual value of the speed threshold (p1226) is
undershot or when the monitoring time (p1227) started when speed setpoint ≤ speed
threshold (p1226) expires.
– Switching on inhibited is activated.
