d2: Frequency Upper and Lower Limits
Use d2 parameters to configure the frequency reference limits.
d2-01
Frequency
Reference Upper
Limit
Sets the frequency reference upper limit as a percentage of maximum
output
frequency (E1-04). Output speed is limited to this value even
if the frequency reference is higher. This limit applies to all frequency
reference sources.

Limit
Sets the frequency reference lower limit as a percentage of maximum
output frequency (E1-04). Output speed is limited to this value even
if the frequency reference is lower. This limit applies to all frequency
reference sources.

d3: Jump Frequency
Use d3 parameters to configure the drive Jump Frequency settings.
d3-01 Jump Frequency 1 d3-01 to d3-04 allow programming of three prohibited frequency
reference points for eliminating problems with resonant vibration of
the motor/machine. This feature does not eliminate the selected
frequency values, but accelerates and decelerates the motor through
the prohibited bandwidth.
The parameters must be according to the rule
d3-01 ≥ d3-02 .

0.0 Hz O 294 92
d3-02 Jump Frequency 2 0.0 Hz O 295 92
d3-04
Jump Frequency
Width
This parameter sets the dead-band width around each selected
prohibited frequency reference point. The bandwidth becomes the
designated Jump frequency, plus or minus d3-04.

d4: Frequency Reference Hold
Use d4 parameters to configure the drive frequency reference hold function.
d4-01
Frequency
Reference Hold
Function Selection
Determines if the frequency reference or frequency reference bias is
saved when the Run command is removed or the power goes off.
0: Disabled
1: Enabled
This parameter is effective when the multi-function inputs “Accel/
Decel Ramp Hold” or “Up/Down” commands are selected (H1-
oo = A or 10/11).
0, 1 0 O 298 93
<1> Parameter can be changed during run.
