Reference
Upper Limit
Determines maximum
frequency reference, set as a
percentage of maximum
output frequency (E1-04). If
the frequency reference is
above this value, actual Drive
speed will be limited to this
value. This parameter applies to
all frequency reference sources.

Jump
Frequency 1
This parameter allow
programming of up to three
prohibited frequency
reference points for
eliminating problems with
resonant vibration of the
motor / machine. This feature
does not actually eliminate
the selected frequency values,
but will accelerate and
decelerate the motor through
the prohibited bandwidth.
