Selection Of Control Type For Closed-Loop Current/Torque Control; Current Limitation Armature Current Limit Torque Dir I Factor; Current Limitation Armature Current Limit Torque Dir Ii Factor - Siemens SINAMICS DCM List Manual

Note: If p50169 = 0:
Current limitation.
If p50169 = 1:
Torque limiting; in other words, the pre-set torque limit is converted into a current limit:
current limit = torque limit/motor flux

Description: Sets the controller's control type (closed-loop current control or closed-loop torque control).
p50170 = 0:
The controller is current-controlled.
p50170 = 1:
The controller is torque-controlled; in other words, the torque setpoint is converted into a current setpoint (current
setpoint = torque setpoint/motor flux).
Value: 0:
1:
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.
If p50169 = 1 and p50170 = 1:
This is an invalid setting. If p50169 = 1, it will not be possible to set p50170 = 1.
Refer to: p50051, p50117, p50173, p50263
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
