Jump frequency 1 Set the center values of the
jump frequencies in%.

ting the jump frequency to 0
Hz. Always ensure that the fol-
lowing applies:
d3-01 ≥ d3-02 ≥ d3-03
Operation in the jump fre-
quency range is prohibited but
during acceleration and decel-
eration, speed changes
smoothly without jump.
