Power Unit Cooling Type / Pu Cool Type; Operating Hours Counter Power Unit Fan / Pu Fan T_Oper; Maximum Operating Time Power Unit Fan / Pu Fan T_Oper Max - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
Warning: Re p0247.5 = 1 (only for induction motors):
If the Voltage Sensing Module (VSM) is connected to the line voltage, then the line frequency is interpreted as speed.
In this case, the flying restart function cannot be used together with VSM and the bit should be set to 0.
If only one VSM is connected at the Motor Module, line synchronization must be deactivated (p3800 = 0), in order to
be able to use flying restart together with VSM. If two VSMs are connected, the second VSM is used for flying restart.
Note: The functions are only available if a Voltage Sensing Module (VSM) is assigned to the Motor Module (p0150, p0151).

Power unit cooling type / PU cool type

VECTOR_G Can be changed: C2(1, 2)
Data type: Integer16
P-Group: Converter
Not for motor type: -
Min
0
Description: Sets the cooling type for booksize compact power units.
This therefore defines whether for these power units, the internal air cooling is shut down and instead, the "Cold-
Plate" cooling type is used.
Value: 0:
1:
Note: For booksize compact power units, there is a 4 at the 5th position in the Order No.
The parameter is irrelevant for all other power unit types.
p0251[0...n]

Operating hours counter power unit fan / PU fan t_oper

B_INF, VECTOR_G Can be changed: T
Data type: Unsigned32
P-Group: Modulation
Not for motor type: -
Min
0 [h]
Description: Displays the power unit fan operating hours.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: p0252
Note: For liquid-cooled chassis power units, the operating hours of the inner fan are displayed in p0251 and not in p0254.
p0252

Maximum operating time power unit fan / PU fan t_oper max

B_INF, VECTOR_G Can be changed: T
Data type: Unsigned32
P-Group: Modulation
Not for motor type: -
Min
0 [h]
Description: Sets the maximum operating time of the power unit fan.
The pre-alarm (warning) is output 500 hours before this set value.
The monitoring is de-activated with p0252 = 0.
Dependency: Refer to: p0251
p0254[0...n] Operating hours counter power unit fan inside the converter / PU inner fan t_op
VECTOR_G Can be changed: T
Data type: Unsigned32
P-Group: Modulation
Not for motor type: -
Min
0 [h]
Description: Displays the power unit fan operating hours of the internal fan in the power unit.
