Armature rated direct current / Arm I_rated

DC_CTRL Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.1 [A]
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.
p51823

Load voltage at armature rated current / V_load Ia_rated

DC_CTRL Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.1000 [V]
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.
