SINAMICS S List Manual (LH1), 07/2007
Description: Sets the monitoring time for the power unit.
The following applies for infeeds and drives:
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, then fault F06000 (infeeds) or F07802 (drives) is output.
For drives, the following also applies:
After the pulse enable (operation enabled, p0852), the monitoring time is re-started. If the infeed does not signal
ready to the drive within the monitoring time (using BI: p0864 of the drive), fault F07840 is initiated.
Dependency: Refer to: F06000, F07802, F07840, F30027
Notice: The maximum time to pre-charge the DC link is monitored in the power unit and cannot be changed. The maximum
duration of the pre-charging depends on the power class and the power unit design.
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 pre-assignment (default) value for p0857 depends on the power class and the design of 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 a fault.
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 (uncondition-
ally 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.
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 (uncondition-
ally open holding brake).
