Parameters
List of Parameters
p1496[0...n]
Acceleration pre-control scaling / a_before scaling
Access level: 3
Can be changed: U, T
Units group: -
Min
0.0 [%]
Description:
Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency:
Refer to: p0341, p0342
Note:
The parameter is set to 100% by the rotating measurement (refer to p1960).
The acceleration pre-control may not be used if the speed setpoint manifests significant ripple (e.g. analog setpoint)
and the rounding-off in the speed ramp-function generator is disabled.
We also recommend that the pre-control mode is not used if there is gearbox backlash.
p1499[0...n]
Accelerating for torque control, scaling / a for M_ctrl scal
Access level: 3
Can be changed: U, T
Units group: -
Min
0.0 [%]
Description:
Sets the scaling for the acceleration integrator at low speeds (only for encoderless torque control).
Dependency:
Refer to: p0341, p0342
p1500[0...n]
Torque setpoint selection / M_set sel
CU240B-2
Access level: 2
Can be changed: C(1), T
Units group: -
Min
0
Description:
Sets the source for the torque setpoint.
For single-digit values, the following applies:
The value specifies the main setpoint.
For double-digit values, the following applies:
The left-hand digit specifies the supplementary setpoint, the right-hand digit the main setpoint.
Example:
Value = 26
--> The analog setpoint (2) supplies the supplementary setpoint.
--> The fieldbus (6) supplies the main setpoint.
