Siemens SINAMICS G120X - Power Unit Main Contactor Holding Time after OFF1; Power Unit Thyristor Rectifier Wait Time; PU Thy_Rect T; Sequence Control Configuration; Seq_Ctrl Config

p0867 Power unit main contactor holding time after OFF1 / PU t_MC after OFF1
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0.0 [ms]
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.

G120X_DP (PM330),
G120X_PN (PM330),
G120X_USS (PM330)
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0 [ms]
Max:
65000 [ms]
Factory setting:
0 [ms]
Description: Sets the debounce time for the DC circuit breaker for power units in the "chassis" format.
Dependency: The parameter is only active for PM330 power units.
Note
The following applies if p0868 = 65000 ms:
The debounce time defined internally in the power unit's EEPROM is implemented.

Dependency: See also: 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.
