5.13 The Control Loop 355
Use machine parameter MP_compFFAdjust to adjust the surface under the
compensation curve as a function of the velocity at the reversal point. The sur-
face entered in the machine parameter
MP_compStrength is valid for the
acceleration entered in MP_compRefAcc. The compensation strength is
increased or decreased during accelerations that differ from the acceleration
in
MP_compRefAcc.
MP_compFFAdjust
Additive correction of the compensation strength with respect
to the machine parameter MP_compStrength
Algebraic sign:
0: The compensation strength is constant over all acceleration
values and is equal to the value in MP_compStrength.
> 0: The surface under the compensation curve becomes larger
for low accelerations.
< 0: The surface under the compensation curve becomes
smaller for low accelerations.

MP_compRefAcc
For the acceleration given here, the surface under to compen-
sation curve is set equal to the value entered in
MP_compStrength.
