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.
Jump Frequency 1 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Fre-
quency 1 (F270).
Jump Frequency 2
Program Special Jump Frequencies
This parameter is the same as Jump Frequency 1
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.
Jump Frequency 2 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Fre-
quency 2 (F272).
