Adjust and Function Specification
§
Cd60 V / F frequency FC (Settable range 0.5-240)
This function cannot be modified during revolution.
To set V/F slope frequency FC when Cd05=11.

Output Frequency
§
Cd61 PWN frequency (Settable range 0-4)
This function cannot be modified during revolution.
This function is to set PWM frequency.
The higher pitch of PWM & the lower noise of motor, however motor might be shave.
The lower pitch of PWM & the higher noise of motor, however motor should be more
stable.

§
Cd62 PWM Frequency (Settable range 15-40)
This function cannot be adjusted during operation.
Ex: Cd62 = 15, PWM Frequency = 1.5KHz
Ex: Cd62 = 30, PWM Frequency = 3.0KHz
§
Cd63 Switch point for 3
rd
phase PWM and 2
nd
phase PWM(Settable range 5-17)
This function is adjustable during revolution
Ex. Cd63 = 5 when output voltage of inverter exceed rated voltage 5%+3%=8%,
inverter output shift from 3
rd
phase PWM to 2
nd
phase PWM. When output voltage
lower than 5% of rated voltage, inverter output shift from 2
nd
phase PWM to 3
rd
phase PWM.
