SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
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.
Description: Sets the scaling for the acceleration integrator at low speeds (only for encoderless torque control).
Dependency: Refer to: p0341, p0342
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.
Value: 0: No main setpoint
2: Analog setpoint
6: Fieldbus
20: Analog setpoint + no main setpoint
22: Analog setpoint + analog setpoint
26: Analog setpoint + fieldbus
60: Fieldbus + no main setpoint
62: Fieldbus + analog setpoint
66: Fieldbus+fieldbus
Dependency: When changing this parameter, the following settings are influenced:
Refer to: p1503, p1511
Caution: When executing a specific macro, the corresponding programmed settings are made and become active.
