CHV100 Series Close Loop Vector Control Inverter

output frequency rise rate because of too big load. If no measures to take, inverter will
trip caused by over-current.
The principle of over-current protection is to detect the output current of inverter during
inverter operation and compare it with over-current stall threshold determined by PB.12.
If it exceeds the value of PB.12 during acceleration, inverter will remain output frequency;
if it exceeds the value of PB.12 during constant speed running, inverter will decrease
output frequency. When output current of inverter is lower than the value of PB.12,
inverter will continue to accelerate until output frequency reach frequency reference.
