SINAMICS DCM
552 List Manual (LH8), 02/2015, 6RX1800-0ED76
Description: Sets the rated direct current for the armature.
The output direct current supported by the power unit in continuous operation should be set in this parameter.
Note: The parameter is only effective on the Control Module.
Description: Sets the load voltage resulting from the following calculation formula:
V_load = R_load * tr * Id
V_load: The load voltage to be set in this parameter
R_load: The load resistance (default 10 ohm)
r: Transformation ratio of the current transformer (I2 / I1)
Id: Output direct current according to parameter p51822
Note: The parameter is only effective on the Control Module.
Description: Sets the configuration for the current transformer for current actual value sensing.
Value: 1: Current transformer in phase U and V
2: Current transformer in phase U and W
3: Current transformer in phase V and W
4: External current transformer connected in V circuit
5: Bipolar current actual value signal (external shunt)
Note: The parameter is only effective on the Control Module.
Description: Sets the power unit type.
Value: 2: 2-quadrant power unit
4: 4-quadrant power unit
Note: The parameter is only effective on the Control Module.
