Jump Frequency 1 Set the center values of the jump frequen-
cies 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 frequency range is
prohibited but during acceleration and
deceleration, speed changes smoothly
without jump.
