Note:
When AC drive running in SVC or VC mode, carrier frequency shall be limit between 2kHz to
8kHz automatically.
d0.02
Range: 0 ~ 1
Default: 1
Carrier frequency
adjustment with
temperature
0: disable
1: enable
It is used to set whether the carrier frequency is adjusted based on the
temperature. When this parameter is set to enable, it can be reduce the
overheat alarms.
d0.03
Range: 0 ~ 10
Default: 0
Random PWM
depth
0: Disable random PWM
>0: setting the depth of random PWM
Random PWM function is enable when this parameter is greater than 0.
It can help to reduce the motor noise.
d0.04
Range: 0.00 ~ Max frequency(b0.00)
Default: 50.00
DPWM
switchover
frequency upper
limit
If the output frequency is higher than this Value + 3Hz, the DPWM
modulation mode is adopted, or else continuous method is adopted.
d0.05
Range: 0 ~ 1
Default: 0
PWM Modulation
mode
0: asynchronous modulation
1: synchronous modulation
