Speed Controller - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

17.5.4 Speed controller

The source of the actual speed value is selected via parameter
766. By default, speed sensor 1 is used as the actual speed source. If speed
Source
sensor 2 of an expansion module is to deliver the actual value signal for the speed
controller, speed sensor 2 must be selected as the source. Alternatively, the speed
controller can derive the actual speed value from the machine model in configura-
tions 4xx and 6xx (

The control of the torque-forming current components is done in the outer control
loop by the speed controller. Via parameter
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.

Parameter Configuration
The actual speed source is speed sensor 1 of the basic
device (factory setting).
The actual speed source is speed sensor 2 of an expansion

module.
The speed controller receives the calculated actual speed
value from the machine model. Can be set in configura-
tions 4xx and 6xx.
Speed synchronization by comparison between the calcu-
lated machine model and speed sensor 1 to increase speed
accuracy. Can be set in configurations 4xx and 6xx. Ad-
justment for parameter
is considered.

The controller is deactivated or the torque-forming
component is zero.
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.
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.
