Jump Frequency 1
Program Special Jump Frequencies
In conjunction with parameter F271, this parameter establishes a user-defined
frequency range: the Jump Frequency and a plus-or-minus value.
During acceleration, the output frequency of the ASD will hold at the lower
level of the Jump Frequency range until the programmed acceleration ramp
reaches the upper level of the Jump Frequency range. At which time the
output frequency of the ASD will accelerate to the upper level of the Jump
Frequency range and continue upward as programmed.
During deceleration, the output frequency of the ASD will hold at the upper
level of the Jump Frequency range until the programmed deceleration ramp
reaches the lower level of the Jump Frequency range. At which time the
output frequency of the ASD will decelerate to the lower level of the Jump
Frequency range and continue downward as programmed.
Once set up and enabled, it is on in all control modes.
User-selected frequencies may be jumped to avoid the negative effects of
mechanical resonance.
Direct Access Number — F270

Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
Jump Frequency 1 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Frequency 1 (see
F270).
Direct Access Number — F271
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — 30.0
Units — Hz
Jump Frequency 2
Program Special Jump Frequencies
Same as Jump Frequency 1 (F270) and is used when multiple frequencies are
to be jumped (see the plus-or-minus value setting at F273). When multiple
jump frequencies overlap, the system will recognize the lowest and the highest
frequencies as one jump range.
Direct Access Number — F272

Jump Frequency 2 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Frequency 2
(F272).
