Description
The AC drive supports two PWM modes: CPWM and DPWM. When the running frequency is higher than
A5-00 (switchover frequency), the DPWM mode is used. When the running frequency is lower than
A5-00 (switchover frequency), the CPWM mode is used. The DPWM mode can improve the AC drive
efficiency, and the CPWM mode can reduce the motor noise.
Increasing the value of this parameter to the maximum frequency will reduce the motor noise.
