Direct Access Parameter Information
Q9 Plus ASD Install/Op Manual
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 pro-
grammed 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 pro-
grammed 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.

Changeable During Run — Yes
Minimum — 0.00
Maximum — Maximum Freq.
(F011)
Units — Hz
Jump Frequency 1 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Fre-
quency 1 (F270).
Direct Access Number —
F271
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — (ASD-Dependent)
Units — Hz
Jump Frequency 2
Program Special Jump Frequencies
This parameter is the 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 fre-
quencies as one jump range.

quency 2 (F272).
