– Reaction as for OFF2
– 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. 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.
– 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 zero speed is detected, the motor brake (if parameterized) is closed.
– The pulses are suppressed when the motor brake application time (p1217) has
elapsed. 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.
