p0857
Power unit monitoring time / PU t_monit
Access level: 3
Can be changed: T
Units group: -
Min
100.0 [ms]
Description:
Sets the monitoring time for the power unit.
The monitoring time is started after an 0/1 edge of the ON/OFF1 command. If the power unit does not return a
READY signal within the monitoring time, fault F07802 is output.
Dependency:
Refer to: F07802, F30027
Notice:
The maximum time to pre-charge the DC link is monitored in the power unit and cannot be changed. The maximum
pre-charging duration depends on the power unit.
The monitoring time for the pre-charging is started after the ON command (BI: p0840 = 0/1 signal). Fault F30027 is
output when the maximum pre-charging duration is exceeded.
Note:
The factory setting for p0857 depends on the power unit.
The monitoring time for the ready signal of the power unit includes the time to pre-charge the DC link and, if rele-
vant, the de-bounce time of the contactors.
If an excessively low value is entered into p0857, then after enable, this results in the corresponding fault.
