Carrier Frequency - Panasonic VF200 Instruction Manual

P128

Carrier Frequency

This carrier frequency can be adjusted to reduce motor noise and avoid
mechanical resonance.
■ When "P129: Vector Control Select" setting = "0" (when V/F control is
selected)
Setting value (kHz)
■ When "P129: Vector Control Select" setting = "1" (when vector control is
selected)
Setting value (kHz)
・This setting can be changed during operation, but the following change
between low frequency group and high frequency group can be made only
when the inverter is stopped.
Low frequency group: 0.8 to 1.6 kHz
High frequency group: 2.5 to 10.0 kHz
・When the carrier frequency is set to 7.5 kHz for a 3.7 KW+ inverter, please
derate the output current according to the limitations on page 132.
・When the carrier frequency is set to 7.5 kHz or 10.0 kHz, it will vary
depending on the output frequency.
For 1-phase 200 V type
1) When set to 7.5 kHz, carrier frequency of 5.0 kHz will be output for
frequency band of 0.5 to 5 Hz.
2) When set to 10.0 kHz, carrier frequency of 5.0 kHz and 7.5 kHz will be
output for frequency band of 0.5 to 5 Hz and 5 to 10 Hz respectively.
For 3-phase 400V type
1) When set to 7.5 kHz, carrier frequency of 5.0 kHz will be output for
frequency band of 0.5 to 10 Hz.
2) When set to 10.0 kHz, carrier frequency of 5.0 kHz and 7.5 kHz will be
output for frequency band of 0.5 to 10 Hz and 10 to 15 Hz respectively.
