After a fault occurs during operation, the inverter stops output and displays the fault code. After the reset interval set by 04.09, the inverter automatically resets the
fault and restarts operation according to the set starting mode.
The number of automatic fault resets is set by 04.08. When the fault reset times is set to 0, there is no automatic reset function and can only be reset manually.
When 04.08 is set to 100, it means that the number of times is unlimited, that is, countless times.
For IPM faults, external device faults, etc., the inverter does not allow self-reset operation.

If the internal DC bus voltage of the frequency inverter is higher than the starting voltage of energy consumption braking, the built-in braking unit will act. If a
braking resistor is connected at this time, the voltage energy raised inside the frequency inverter will be released through the braking resistor, and the DC voltage will
fall down.

The over-modulation function means that the inverter increases the output voltage by adjusting the utilization rate of the bus voltage. When the over-modulation is
effective, the output harmonics will increase. If long-term low-voltage and heavy-load operation or high-frequency (over 50HZ) operating torque is insufficient, this
function can be turned on.

The current output is stable, and the full-band power tube generates a lot of heat.
1: Full frequency five bands
The current output is stable, and the power tube generates a small amount of heat
2: Seven segments to five segments
The current output is stable, the low-frequency power tube heats up more, and the high-frequency power tube heats up less.

After the asynchronous motor is loaded, the speed will decrease. The use of slip compensation can make the motor speed close to its synchronous speed, so
that the motor speed control accuracy is higher. This coefficient is only for ordinary V/F mode.
