Parameter 04.011 Torque Mode Selector
Short description Defines the torque mode used by the drive
Mode Open‑loop

Coding RW
If TorqueModeSelector (04.011) = 0 the ramp system defines the PostRampReference (02.001) unless the current limits are active, and so the motor
is frequency controlled. If TorqueModeSelector (04.011) = 1 the torque controller defines the PostRampReference (02.001), and so the motor is
torque controlled.
Parameter 04.013 Current Controller Kp Gain
Short description Defines the current loop controller proportional gain
Mode Open‑loop
Minimum 0.00 Maximum 4000.00
Default 20.00 Units

Coding RW
CurrentControllerKpGain (04.013) and CurrentControllerKiGain (04.014) are the proportional and integral gains of the current controller.
Refer to Torqueandcurrentcontrol .
Parameter 04.014 Current Controller Ki Gain
Short description Defines the current loop controller integral gain

A single time constant thermal model is provided that can be used to estimate the motor temperature as a percentage of its maximum allowed
temperature. The input to the model is the CurrentMagnitude (04.001). Throughout the following discussion MotorRatedCurrent (05.007) is used in the
