16.5.3 Speed controller
The source of the actual speed value is selected via parameter Actual Speed
Source
766. By default, speed sensor 1 is used as the actual speed source. If speed
sensor 2 of an extension module is to deliver the actual value signal for the speed
controller, speed sensor 2 must be selected as the source.
Actual Speed Source 766 Function
1 - Speed Sensor 1
The actual speed source is speed sensor 1 of the
basic device (factory setting).
2 - Speed Sensor 2
The actual speed source is speed sensor 2 of an
extension module.

Only available if extension module is installed
The control of the torque-forming current components is done in the outer control
loop by the speed controller. Via parameter
Operation Mode 720, you can select the
operation mode for the speed controller. The operation mode defines the use of the
parameterizable limits. These are referred to the direction of rotation and the direc-
tion of the torque and depend on the selected configuration.
Operation mode 720 Function
0 - Speed Controller Off
The controller is deactivated or the torque-forming
component is zero.

Limits for
Motor / Generator
The limitation of the speed controller assigns the up-
per limit to the motor operation of the drive. Inde-
pendent of the direction of rotation, the same limit is
used. The same applies in the case of regenerative
operation with the lower limit.
2 -
Limits for
pos. / neg. Torque
The assignment of the limit is done by the sign of the
value to be limited. Independent of the motor or gen-
erator operating points of the drive, the positive limi-
tation is done by the upper limit. The lower limit is
regarded as a negative limitation.
