SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
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.
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 to select the "parking axis" function.
Dependency: BI: p0897 = 0 signal
The function "parking axis" is not selected.
BI: p0897 = 1 signal
The function "parking axis" is selected.
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: After it has been selected the "parking axis" function only becomes active when the pulses are suppressed.
