BONFIGLIOLI ACTIVE Cube ACU 401-25 User Manual

17.5.4 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 expansion module is to deliver the actual value signal for the speed
controller, speed sensor 2 must be selected as the source. Alternative
ly, the speed
controller can derive the actual speed value from the machine model in configura-
tions 4xx and 6xx (Parameter Configuration 30).
Operation mode 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 expansion
module.
1)
3 - Machine Model
The speed controller receives the calculated actual speed
value from the machine model. Can be set in configura-
tions 4xx and 6xx.
4 - Speedtracking EC 1
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
Integral Time Speedtracking 515
is considered.
5 - Speedtracking EC 2
Speed synchronization by comparison between the calcu-
lated machine model and speed sensor 2 of an expansion
module to increase speed accuracy. Can be set in configu-
rations 4xx and 6xx. Adjustment for parameter
Integral
Time Speedtracking 515 is considered.
1)
Only available if expansion 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.
1 -
Limits
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
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.
