Note
This bit is used to initiate a response for the drives when the control fails (F07220). If there is no control available, then
binector input p0854 should be set to 1.
If a control is available, then STW1.10 must be set to 1 (PZD1) so that the received data is updated. This applies
regardless of the setting in p0854 and even in the case of free telegram configuration (p0922 = 999).

10000.0 [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: See also: F07802, F07840, F30027
NOTICE
The maximum time to precharge the DC link is monitored in the power unit and cannot be changed. The maximum
precharging duration depends on the power unit.
The monitoring time for the precharging is started after the ON command (BI: p0840 = 0/1 signal). Fault F30027 is
output when the maximum precharging 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 precharge the DC link and, if relevant,
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.

Description: Sets the signal source for the feedback signal from the line contactor.
Recommendation: When the monitoring is activated (BI: p0860 not equal to r0863.1), then to control the line contactor, signal BO: r0863.1
of its own drive object should be used.
Dependency: See also: p0861, r0863
See also: F07300
NOTICE
The line contactor monitoring is deactivated if the control signal of the particular drive object is set as the signal source
for the feedback signal of the line contactor (BI: p0860 = r0863.1).
Note
The state of the line contactor is monitored depending on signal BO: r0863.1.
When the monitoring is activated (BI: p0860 not equal to r0863.1), fault F07300 is then also output if the contactor is
closed before it is controlled using r0863.1.
