Adjusting Output Voltage
To set parameters of FC-15 is to adjust the output voltage of inverter.
If input voltage is 380VAC, and if FC-15 is set as 58.00, it refers that the motor (220V Input)
can be applied. The rated current of motor (220V input) shall not be bigger than the rated
output current of inverter.
Remarks:
The function is disabled in SVC mode.

〇
Braking unit works in PWM mode at dynamic braking. FC-16 is for setting the duty ratio of
braking unit. The bigger the setting value of FC-16 is, the stronger the brake capability is.
When setting brake duty ratio, please take the resistance and capacity of braking resistor. The
function is only for the built-in braking unit.

If input voltage of inverter < output voltage, the utility of DC bus will be improved by
increasing over-modulation coefficient so that the upper limit of output voltage will be
increased. When FC-17=1.10, it refers to that the upper limit of output voltage will be 10%
higher.
