Short Description | Position Control Loop: Feed Forward for Current Setpoint | |||
Description
Position control loop: feed forward for the current setpoint. Has to be set, that the contouring error is minimized.
This parameter is only used for the PI position control loop (EXTPOS=0, 2).
In addition to that, the parameter has effect with starting firmware 4.78 using table based motion task enabled with bit in O_C and using SPSET = 3.
If GV is changed after optimizing GPFFT, GPFFT must be changed also inversely proportional.
