Detailed instruction of parameters
two-phase modulation
1: PWM mode 2, three-phase modulation
LED tens: low-speed carrier frequency limit
mode
0: Low-speed carrier frequency limit mode 1, the
carrier frequency will limit to 1k or 2k if it exceeds
2k at low speed
1: Low-speed carrier frequency limit mode 2, the
carrier frequency will limit to 4k if it exceeds 4k at
low speed
2: No limit
LED ones
0: Disabled
1: Enabled
LED tens
0: Light overmodulation; restricted in zone 1
1: Heavy overmodulation; restricted in zone 2
For VFDs of 1PH 220V/3PH 380V (≤2.2kW) and
3PH 220V (≤0.75kW), the default value is 00;
for those of 3PH 380V (≥4kW) and 3PH 220V
(≥1.5kW), the default value is 01.
