Chapter 4: AC Drive Parameters
Minimum Output Voltage Mem Addr 0207H(40520)
Range: 2.0 to 50.0V Default Setting: 10.0
•This parameter sets the Minimum Output Voltage of the AC drive.
This parameter must be equal to or less than Mid-Point Voltage (2-05).
PWM Carrier Frequency Mem Addr 0208H(40521)
Range: 3 to 10 KHz Default Setting: 10
• This parameter sets the carrier frequency of PWM (Pulse-Width Modulated) output.
• In the table below, we see that the carrier frequency of PWM output has a
significant influence on the electromagnetic noise, leakage current, heat
dissipation of the AC drive and the acoustic noise to the motor
