Selects the number of pulses per second of
the output voltage waveform. Setting range
determined by C6-01 setting.
0: Low 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
F: Program (Determined by the settings of
C6-03 thru C6-05) Carrier Frequency Selection
C6-02
2.0 to 15.0 kHz Carrier Frequency Upper
Limit C6-03
0.4 to 15.0 kHz Carrier Frequency Lower
Limit C6-04
054 Carrier frequency 1, 2, 4 ~ 6: carrier freq = set value * 2.5 Khz
3: Carrier frequency =8kHz
7, 8, 9: The output freq of 2.5kHz or less is
proportional to the carrier frequency.
(7: 12*fout ,8: 24*fout, 9:36*fout)
10: Carrier frequency =7kHz
(Only 400V 45kW)
0 to 99
Sets the relationship of output frequency to
carrier frequency when C6-02 = F.

055 Operation after
momentary power
loss 0: Not Provided.
1: Operation continues after power recovery
within 2 sec
2: Operation continues while control power is
on ( UV1, UV3 faults not are detected) Enables and disables the momentary power
loss function.
0: Disabled - Drive trips on (UV1) fault
when power is lost.
1: Power Loss Ride Thru Time - Drive will
restart if power returns within the time
set in L2-02.*
2: CPU Power Active - Drive will restart if
power returns prior to control power
supply shut down.*
* In order for a restart to occur, the run
command must be maintained throughout
the ride thru period.

057 Minimum base block time Set unit: 0.1sec
Set range: 0.5-10.0sec 0.1 to 5.0sec
Sets the minimum time to wait to allow the
residual motor voltage to decay before the
Drive output turns back on during power
loss ride thru. After a power loss, if L2-03
is greater than L2-02, operation resumes
after the time set in L2-03.

059 Power ride through
time Set unit: 0.1sec and set range: 0.0-2.0sec 0.0 to 25.5sec
Sets the power loss ride-thru time. This
value is dependent on the capacity of the
Drive. Only effective when L2-01 = 1. Momentary Power Loss
