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

Master Speed
Set the master speed

Jump
This parameter allow
Frequency 1
programming of up to three
prohibited frequency
Jump Freq 1
reference points for
eliminating problems with
Jump
resonant vibration of the
Frequency 2
motor / machine. This feature
Jump Freq 2
does not actually eliminate
the selected frequency values,
Jump
but will accelerate and
Frequency 3
decelerate the motor through
Jump Freq 3
the prohibited bandwidth.
Jump
This parameter determines
Frequency
the width of the deadband
Width
around each selected
prohibited frequency
reference point. A setting of
Jump
"1.0" will result in a
Bandwidth
deadband of +/- 1.0Hz.
