【F1.21】 Switching Frequency
a. The settings are listed in the below table:
Setting Value Switching frequency
0 800Hz
1 2.5kHz
2 5kHz
3 7.5kHz
4 10kHz
5 12.5kHz
6 16kHz
b. De-rate the output current of drive if the switching frequency setting value is over 4.
c. The higher switching frequency has less noise. But using higher switching
frequency must consider the cable length between drive and motor and must be
adjusted according the connection distance between drive and motor (see wiring
installation in section 2-3-4)
d. Switching frequency limit: The limit of switching frequency will be auto-adjusted
according to the load condition (see the below diagram for load condition vs.
switching frequency auto-de-rating).
e. The setting value of switching frequency is higher and the motor noise is lower.
【F1.22】 Overload Decrease Switching Frequency
The settings are listed as below:
0：The switching frequency will not be adjusted by the load of current.
1：The swithching frequency will be auto-adjusted according to the load of
current.
