Description: Sets the scaling for the acceleration precontrol of the speed/velocity controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0341, p0342
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.
Description: Displays the torque setpoint before entering the supplementary torque.
For closed-loop speed control, r1508 corresponds to the speed controller output.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Description: Sets the smoothing time constant of the accelerating torque.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The acceleration precontrol is inhibited if the smoothing is set to the maximum value.
Description: Displays the accelerating torque for precontrol of the speed controller.
Index: [0] = Unsmoothed
[1] = Smoothed
