B2-01 PWM method 0~1 0
☆
0: Asynchronous modulation;
1: Synchronous modulation, only valid for VF control control mode, and the operating frequ-
ency is higher than 85Hz;
Synchronous modulation means that the carrier frequency of the inverter changes linearly
with the output frequency, and is generally used at a higher frequency, which is beneficial to
improve the quality of the output voltage. The asynchronous modulation is that the carrier
frequency is constant, and the asynchronous modulation effect is better at low frequencies.

PWM seven-segment/five-
segment selection
0~1 0
☆
0: 7 segments in the whole process;
1: Seven-segment/five-segment automatic switching;
When the PWM seven-stage continuous modulation is used, the switching loss of the invert-
er is large, but the current ripple is small; in the 5-stage intermittent debugging mode, the sw-
itching loss is small, the current ripple is large, and the motor noise increases.

B2-03 CBC current limit enable selection 0~1 1
☆
0: Disable;
1: Enable, at this time, the overcurrent fault of the inverter can be reduced to a great extent,
so as to realize uninterrupted operation. If the inverter will fault Err33 when the current is lim
-
ted rapidly for a long time, it means that the inverter is overloaded and needs to stop.
