F270
Jump Frequency 1
Program Special Jump Frequencies
In conjunction with 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 drive will hold at the frequency
of the lower level of the Jump Frequency range until the programmed
acceleration ramp reaches the upper level of the Jump Frequency range. Then,
the output frequency of the drive will accelerate to the upper level of the Jump
Frequency range and continue upward as programmed.
During deceleration, the output frequency of the drive will hold at the
frequency of the upper level of the Jump Frequency range until the
programmed deceleration ramp reaches the lower level of the Jump Frequency
range. Then, the output frequency of the drive 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 Frequency 1
(F270).
Jump Frequency 2
Program Special Jump Frequencies
This parameter is the same as Jump Frequency 1
multiple frequencies are to be jumped (see the plus-or-minus value setting at
Jump Frequency 2 Bandwidth (F273). When multiple jump frequencies
overlap, the system will recognize the lowest and the highest frequencies as one
jump range.
Jump Frequency 2 Bandwidth
Program Special Jump Frequencies
This parameter establishes a plus-or-minus value for Jump Frequency 2
(
F272).
Jump Frequency 3
Program Special Jump Frequencies
This parameter is the same as Jump Frequency 1
multiple frequencies are to be jumped (see the plus-or-minus value setting at
Jump Frequency 3 Bandwidth (F275). When multiple jump frequencies
overlap, the system will recognize the lowest and the highest frequencies as one
jump range.
