2 Parameters
2.2 List of parameters
p50112[0...n]

Field circuit resistance / R_field circuit

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.000 [ohm]
Description: Sets the field circuit resistance.
Note: The parameter is set automatically during the optimization run for closed-loop field current control (p50051 = 24).
p50113[0...n]

Motor I2t monitoring continuous current factor / Mot I2t I_cont

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.50
Description: Sets the permissible continuous armature current for motor I2t monitoring.
Note: At this permissible continuous current, fault F60037 is not output.
The current is calculated as follows: p50113 * p50100.
p50114[0...n]

Motor thermal time constant / Mot T therm

DC_CTRL Can be changed: C2(1), U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [s]
Description: Sets the thermal time constant of the motor.
Note: Value = 0:
The motor's I2t monitoring is de-activated.
p50115[0...n]

Speed controller EMF at maximum speed / EMF at n_max

DC_CTRL Can be changed: C2(1), U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
1.00 [%]
Description: Setting of the percentage value in relation to p50078[0] for specifying the EMF at maximum speed.
The speed is adjusted using the EMF as the speed actual value.
p50116[0...n] Field circuit inductance / L_field circuit
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [mH]
Description: Sets the field circuit inductance.
Dependency: Refer to: p51597
