Powering-up the drive
– 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 if the actual speed drops below the threshold (p1226) or if the
monitoring time (p1227) started when the speed setpoint ≤ speed threshold (p1226)
has expired.
