SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Enters scaling of acceleration in [%].
The response of setpoint changes for the speed control loop can be improved using the precontrol function
(P1496).
Precontrol is derived from the differential frequency setpoint multiplied by the mass inertia P0341; P0342 is then
supplied as a torque setpoint to the current controller.
If the filter (VC: P1442, SLVC: P1452) is applied in the correct manner, the derived speed controller is only required
to control a small deviation in the value of the corrected variable.
Note: P1496 = 0: ==> Precontrol disabled
P1496 > 0: ==> Precontrol enabled
P1496 = 100: ==> Standard setting for precontrol

Note: P1496 = 0: ==> Precontrol disabled (necessary for robustness of safety applications with SS1 and SLS)
P1496 > 0: ==> Precontrol enabled
P1496 = 100: ==> Standard setting for precontrol
Description: Enters scaling of acceleration in [%] for sensorless torque control (SLVC) at low frequencies.
