Carrier Frequency Selection
CarrierFreq Sel
Carrier frequency sets the number of pulses per second of the out-
put voltage waveform.
0: Low Noise (Carrier frequency is randomly moduled for lower
audible noise)
1: Fc = 2.0 kHz
2: Fc = 5.0 kHz
3: Fc = 8.0 kHz
4: Fc = 10.0 kHz
5: Fc = 12.5 kHz
6: Fc = 15.0 kHz

Reference Limits
d2-01
Frequency Reference Upper
Limit
Ref Upper Limit
Determines maximum speed command, set as a percentage of
parameter E1-04. If speed command is above this value, actual
drive speed will be limited to this value. This parameter applies to
all speed command sources.
0.0 to 110.0 100.0% Quick Setting
d2-02
Frequency Reference Lower
Limit
Ref Lower Limit
Determines minimum speed command, set as a percentage of
parameter E1-04. If speed command is below this value, actual
drive speed will be set to this value. This parameter applies to all
speed command sources.
0.0 to 110.0 0.0% Quick Setting
d2-03
Master Speed Reference
Lower Limit
Ref1 Lower Limit
Determines the minimum speed command, set as a percentage of
parameter E1-04. If speed command is below this value, actual
drive speed will be set to this value. This parameter only applies to
analog inputs A1 and A2.
0.0 to 110.0 0.0% Programming
Jump Frequencies
d3-01
Jump Frequency 1
Jump Freq 1
These parameters allow programming of up to three prohibited
frequency 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.

Jump Frequency Width
Jump Bandwidth
This parameter determines the width of the deadband around each
selected prohibited frequency point. A setting of “1.0” will result in
a deadband of +/- 1.0 Hz.
0.0 to 20.0 1.0Hz Programming
Denotes that parameter can be changed when the drive is running.
