Description: Sets the main contactor holding time after OFF1
Dependency: Refer to: p0869
Note: After withdrawing the OFF1 enable (source of p0840), the main contactor is opened after the main contactor holding
time has elapsed.
For p0869 = 1 (keep main contactor closed for STO), after withdrawing STO, the switching on inhibited must be
acknowledged via the source of p0840 = 0 (OFF1) – and before the main contactor holding time expires, should go
back to 1, otherwise the main contactor will open.
When operating a drive connected to SINUMERIK, which only closes the main contactor with the OFF1 command
(blocksize, chassis), p0867 should be set as a minimum to 50 ms.
Description: Sets the debounce time for the DC circuit breaker for power units in the "chassis" format.
Note: The following applies if p0868 = 65000 ms:
The debounce time defined internally in the power unit's EEPROM is implemented.
Description: Sets the configuration for the sequence control.
Dependency: Refer to: p0867
Note: For bit 00:
After withdrawing the OFF1 enable (source of p0840), the main contactor is opened after the main contactor holding
time has elapsed.
For p0869.0 = 1, after withdrawing STO, the switching on inhibited must be acknowledged via the source of p0840 =
0 (OFF1) – and before the main contactor holding time expires (p0867), should go back to 1, otherwise the main
contactor will open.
Description: Sets the signal source to close the main contactor.
Note: The main contactor is also closed when the converter is switched on after issuing the necessary enable signals. A
binector input p0870 = 1 signal prevents the main contactor from being opened when enable signals are withdrawn.
