Parameter setting P52_ "Power off control"
Program a MOVIDRIVE
®
binary input (P60_/P61_) to "Power on" to enable evaluation
of an external power on signal. The ready signal from the MOVIDRIVE
®
MDR60A re-
generative power supply unit is used as the power on signal.

5.2.1
P520 Power off response time
Setting range: 0 – 5 s (step width: 0.1 s)
Use this parameter to set the delay time. There will be no response to a power failure
during the delay period. The power off response time must be set to
≥
300 ms because
the ready signal of the regenerative power supply unit is set to a "0" signal for 200 ms in
the event of brief power supply system failures. The delay time is not effect when P520
< 300 ms.
5.2.2
P521 Power off response
Setting range: CONTROL.INHIBIT EMERGENCY STOP
The power off response takes effect if the power on signal = "0" and the power off re-
sponse time has elapsed. The power off response does not produce an error message
in the inverter. The following settings can be made:
• CONTROLLER INHIBIT
The output stage is inhibited (= high-resistance) and the brake is applied or a motor
without a brake coasts to a stop. The drive restarts when the power on signal = "1".
• EMERGENCY STOP
A stop is initiated using the emergency stop ramp (t14/t24). The brake is applied
when the start/stop speed (P300/P310) is reached. The emergency stop is inter-
rupted and the drive restarted if the power on signal changes to "1" during the stop-
ping procedure.
