p1496[0...n] Acceleration pre-control scaling / a_before scaling
Access level: 3
Can be changed: U, T
Min
0.0 [%]
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency: When the reference model is activated (p1400.3 = 1) and for an internal acceleration pre-control (p1400.2 = 0), the
acceleration pre-control is switched out (disabled). The reference model (p1400.3 = 1) and external acceleration
pre-control (p1400.2 = 1) can be operated together.
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
Min
0.0 [%]
Description: Sets the scaling for the acceleration integrator at low speeds (only for encoderless torque control).
Dependency: Refer to: p0341, p0342

CU230P-2 CAN Access level: 2
Can be changed: C(1), T

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.

Note: With PROFIBUS / PROFINET Control Units, p0922 = 999 must be set so that the command and setpoint sources
can be changed.
