2.2 List of parameters
p50173[0...n] BI: Signal source for closed-loop current/torque control ctr type / Ctr I/tq ctr sig s
DC_CTRL Can be changed: T
Data type: Unsigned32 / Binary
P-Group: -
Not for motor type: -
Min
-
Description: Sets the signal source for changeover between closed-loop current control and closed-loop torque control.
p50170 = 0 and p50173 = 0 signal:
The controller is current-controlled.
p50170 = 1 or p50173 = 1 signal:
The controller is torque-controlled; in other words, the torque setpoint is converted into a current setpoint (current
setpoint = torque setpoint/motor flux).
Dependency: If p50169 or p50170 is set to a value of 1, there must be a valid field characteristic (p50117 = 1); otherwise fault
F60055 will be output on power-up. If this setting is selected, the optimization run for field weakening must be
performed in advance (p50051 = 27).
Parameter p50263 defines the input variable for determining the motor flux.
Refer to: p50170
Note: The following parameters are used to change over between current control and torque control:
- Signal source via connector input p50173
or
- Fixed set value in p50170
p50174 Torque limiting for OFF1 & OFF3 / T_lim OFF1 & OFF3
DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Value = 0 --> torque limiting is not bypassed for OFF1 & OFF3
Value = 1 --> torque limiting bypass active for OFF1 & OFF3
Factory setting = 1 (for compatibility reasons)
Value: 0:
1:
Dependency: Refer to: r52133, r52147
p50175[0...n] CI: Signal source for closed-loop armature current control P gain / Ia ctr Kp sig s
DC_CTRL Can be changed: T
Data type: Unsigned32 / FloatingPoint32
P-Group: -
Not for motor type: -
Min
-
Description: Sets the signal source for variable control of the armature current controller's P gain.
Dependency: Refer to: p50155
Note: The P gain (Kp) for the armature current controller is calculated as follows:
Kp = p50155 x |p50175|
