Speed controller

720 Operation mode (speed controller)
The control of the torque-forming current components is done in the outer control loop by the speed
controller. Via parameter
troller. The operation mode defines the use of the parameterizable limits. These are referred to the
direction of rotation and the direction of the torque and depend on the selected configuration.

The properties of the speed controller can be adapted for adjustment and optimization of the control-
ler.
The amplification and integral time of the speed controller can be set via parameters

Operation Mode
The controller is deactivated or the torque-forming component is
zero.
The limitation of the speed controller assigns the upper limit to the
motor operation of the drive. Independent of the direction of rota-
tion, the same limit is used. The same applies in the case of regener-
ative operation with the lower limit. Factory setting.
The assignment of the limit is done by the sign of the value to be
limited. Independent of the motor or generator operating points of
the drive, the positive limitation is done by the upper limit. The lower
limit is regarded as a negative limitation.
