Set the center values of the
jump frequencies in Hz.
This function is disabled by
setting the jump frequency to
0 Hz. Always ensure that the
following applies:
d3-01 ≥ d3-02 ≥ d3-03
Operation in the jump fre-
quency range is prohibited
but during acceleration and
deceleration, speed changes
smoothly without jump.
