User Manual EM303B General Purpose Inverter 8.13.9 Output Voltage Control 8.13.10 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. 8.13.11 Brake Duty Ratio 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. 8.13.12 Over-modulation Coefficient If input voltage of inverter 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. 8.13.13 Voltage Control FC-18 ones place=0 AVR disabled Output voltage varies with the changes of input voltage or DC bus voltage. 150 No. Function Range Unit Default Type FC-15 Output Voltage 0.00～100.00 % 100.00 ● No. Function Range Unit Default Type FC-16 Brake Duty Ratio 5.00～100.00 % 80.00 〇 No.
