2.2 List of parameters
Note: If value = 0:
The integral component of the armature current controller is kept constantly at zero (i.e. the armature current
controller functions solely as a proportional controller).
Description: Sets the P gain of the armature current controller.
Dependency: Refer to: p50175
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).
The P gain (Kp) for the armature current controller is calculated as follows:
Kp = p50155 x |p50175|
Description: Sets the integral time of the armature current controller.
Dependency: Refer to: p50176
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).
The integral time (Tn) for the armature current controller is calculated as follows:
Tn = p50156 x |p50176|
Description: Selection of the current setpoint integrator.
Value: 0: Reduced gearbox stressing
1: Current setpoint integrator
Note: If value = 0:
The integrator is only effective after a change in torque direction (only functions as a ramp-function generator for the
current setpoint until the first time the output reaches the setpoint at the integrator input after a change in torque
direction).
If value = 1:
The integrator is always effective (functions as a ramp-function generator for the current setpoint).
