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.
p0858[0...n] BI: Unconditionally close holding brake / Uncond close brake
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for the command "unconditionally close holding brake".
Dependency: Refer to: p0855
Note: The signal via BI: p0858 (unconditionally close holding brake) has a higher priority than via BI: p0855 (unconditionally
open holding brake).
For a 1 signal via BI: p0858, the command "unconditionally close the holding brake" is executed and internally a zero
setpoint is entered.
p0860 BI: Line contactor feedback signal / Line contact feedb
Access level: 3
Can be changed: T
Unit group: -
Min
-
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: Refer to: p0861, r0863
Refer to: F07300
Notice: The line contactor monitoring is de-activated 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.
p0861 Line contactor monitoring time / LineContact t_mon
Access level: 3
Can be changed: T
Unit group: -
Min
0 [ms]
Description: Sets the monitoring time of the line contactor.
This time starts each time that the line contactor switches (r0863.1). If a feedback signal is not received from the line
contactor within the time, a message is output.
Dependency: Refer to: p0860, r0863
Refer to: F07300
Note: The monitoring function is disabled for the factory setting of p0860.
