P128: Carrier Frequency - Panasonic VF100 Instruction Manual

P128£ºCarrier frequency
This carrier frequency can be changed to "reduce motor noise" and to" avoid mechanical resonance".
¡ö Setting value of parameter "P129: Vector control select" is "0". (When V/F control is selected.)
Data setting value (kHz)
¡ö Setting value of parameter "P129: Vector control select" is "1". (When vector control is selected.)
Data setting value (kHz)
Note
•E This setting can be changed during operation, but the following groups [Low frequency group]
and [High frequency group] can be set only when the operation is stopped.
[Low frequency group]
[High frequency group]
•E When data value is set to "10.0", the carrier frequency can be used only in the case that the
rated output current of the 3.7kW inverter is decreased. Always refer to precautions on the
usage on page 202.
•E When the carrier frequency is set to 7.5 kHz or 10.0 kHz, the carrier frequency will change
depending on the output frequency.
1) When it is set to 7.5 kHz, the carrier frequency will be output at 5.0 kHz for the output frequency
in the range of 0.5 to 10Hz.
2) When it is set to 10.0 kHz, the carrier frequency will be output at 5.0 kHz for the output frequency
in the range of 0.5 to 10Hz, and at 7.5 kHz for the one in the range of 10 to 15Hz.
•E When data value is set to "10.0", the carrier frequency can be used only in the case that the
rated output current of the 3.7kW inverter is decreased.
Overcurrent trip prevention function (page 73) is invalid.
0.8, 1.1, 1.6, 2.5, 5.0, 7.5, 10.0 (Seven types of settings are possible.)
2.5, 5.0, 7.5, 10.0 (Four types of settings are possible.)
0.8~1.6 kHz
2.5~10.0 kHz
