Co: Torque Setpoint Before Supplementary Torque / M_Set Bef. M_Suppl; Accelerating Torque Smoothing Time Constant / M_Accel T_Smooth; Co: Accelerating Torque / M_Accel; Co: Torque Limit Upper / M_Max Upper - Siemens SINAMICS G120X Operating Instructions Manual

Parameters
7.2 Parameter list
WARNING
The acceleration precontrol r1518 is kept at the old value if the ramp-function generator tracking (r1199.5) is active or
the ramp-function generator output is set (r1199.3). This is used to avoid torque peaks. Depending on the application,
it may therefore be necessary to disable the ramp-function generator tracking (p1145 = 0) or the acceleration
precontrol (p1496 = 0).
The acceleration precontrol is set to zero, if the Vdc control is active (r0056.14/15).
Note
The parameter is set to 100% by the rotating measurement (refer to p1960).
The acceleration precontrol 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 precontrol mode is not used if there is gearbox backlash.
r1508

CO: Torque setpoint before supplementary torque / M_set bef. M_suppl

Access level: 2
Can be changed: -
Unit group: 7_1
Min:
- [Nm]
Description: Displays the torque setpoint before entering the supplementary torque.
For closed-loop speed control, r1508 corresponds to the speed controller output.
p1517[0...n]

Accelerating torque smoothing time constant / M_accel T_smooth

Access level: 4
Can be changed: T, U
Unit group: -
Min:
0.00 [ms]
Description: Sets the smoothing time constant of the accelerating torque.
Note
The acceleration precontrol is inhibited if the smoothing is set to the maximum value.
