p0867 Power unit main contactor holding time after OFF1 / PU t_MC after OFF1
Access level: 3 Calculated: - Data type: FloatingPoint32

Min:

Max:
500.0 [ms]
Factory setting:
50.0 [ms]
Description: Sets the main contactor holding time after OFF1
Dependency: See also: 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.
