Power Unit Contactor Monitoring Time / Pu Cont T_Monit; Co/Bo: Power Unit Contactor Inputs/Outputs Status / Pu Contact Io Stat - Siemens SINAMICS G150 Manual

The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Note: For liquid-cooled chassis power units, the operating hours of the inner fan are displayed in p0251 and not in p0254.

Power unit contactor monitoring time / PU cont t_monit

B_INF, VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
-1 [ms]
Description: Sets the monitoring time for internal monitoring of the contactor feedback contacts.
For a value 0.0 or negative values, the particular monitoring is deactivated.
Re index 0 ... 3:
Is used to monitor the delay time between the control and feedback signals of the particular contactor.
Re index 4 ... 7:
Is used for simultaneity monitoring for a parallel connection. After a contactor has been opened or closed, this checks
whether, after the monitoring time has expired, all contactors of the parallel connection have assumed the same
state.
Re Index 2, 3:
The value -1.0 means that the particular opening time is taken from Index 0 or 1.
Index: [0] = Pre-charging contactor closing time
[1] = Bypass contactor closing time
[2] = Pre-charging contactor opening time
[3] = Bypass contactor opening time
[4] = Simultaneity pre-charging contactor closing time
[5] = Simultaneity bypass contactor closing time
[6] = Simultaneity pre-charging contactor opening time
[7] = Simultaneity bypass contactor opening time
Dependency: Refer to: r0256
Notice: Re index 4 ... 7:
The simultaneity monitoring is only activate after parameter save and POWER ON.
Note: - This parameter is only effective for chassis power units with 3 AC line connection and line contactors.
- The simultaneity monitoring can only be activated for a parallel connection.
- The feedback signal input of an open bypass contactor must be displayed in r0256 = 0.
- The feedback signal input of an open pre-charging contactor must be displayed in r0256 = 1.
- Determining practical monitoring times can be supported by a tracing r0256.
For power unit firmware version less than 4.6, the following applies:
There are no separate monitoring times for the delay time between opening and closing. In this case, the maximum
of the opening time and closing time is effective.
