Built-in reactor

The reactor built in the FREQROL-A201 series is intended to stabilize operation of the converter circuit and differs from the FR-BAL. Note that when performi... More Details >>

Inverter circuit breaker selection

Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Current value on input side and output side

1. When slight imbalance (approximately 5%) is present with the inverter power supply voltage, the inverter input current can get imbalanced significantly. I... More Details >>
