– Response as for OFF2
– No separate braking response; the braking response is provided 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.
– 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 standstill 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.
– Switching on inhibited is activated.
