Armature Voltage Sensing Configuration / Va_Sens Config; Armature Voltage Sensing Analog Input Reference Voltage; Capacitance Of The Dc Link Capacitor / Capac_Dclink - Siemens SINAMICS DCM List Manual

2 Parameters
2.2 List of parameters
Dependency: Refer to: p51823, p51824
Danger: The following applies for p51852 > 0:
Incorrect setting of parameter p51853 leads to damaging or destruction of the power unit!
Note: The following applies for the DC converter:
p51852 = 0: p51853 is not active
p51852 > 0: p51853 is active
The following applies for the Control Module:
p51852 = 0: p51823 is active
p51852 > 0: p51853 is active, p51823 is not active
p51854

Armature voltage sensing configuration / Va_sens config

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets the configuration for the armature voltage sensing.
Value = 0:
The device-internal armature voltage sensing is effective.
Value = 1:
An external armature voltage sensing is entered via analog input 2 (X177.29/30). The device-internal armature
voltage sensing is not effective.
Value = 2: both
Value: 0:
1:
2:
Dependency: Refer to: p51823, p51824
Notice: The following applies for p51854 = 0 --> 1 or 2:
The device must be restarted. Only then does the armature voltage sensing operate correctly via analog input 2.
Note: AI: Analog Input
p51855 Armature voltage sensing analog input reference voltage / Va_sens AI V_ref
DC_CTRL Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
10.000 [V]
Description: Sets the armature voltage, which corresponds to a +10 V voltage at analog input 2 (X177.29/30).
Dependency: Refer to: p51854
Note: The parameter is only effective for p51854 = 1.
