Fault code

Regenerative overvoltage protection (E.OVT).This error occurs when the regenerative power returns from the motor to the inverter (for example, during deceler... More Details >>

Clutch connection of load

Since a large load is applied to the motor when the electromagnetic clutch turns on, overcurrent may occur if the load is heavy. To ensure that the rated cur... More Details >>

Power factor of inverter drive

Under 100% load, the power factors of the AC and DC reactors are 90% and 95%, respectively. For a line with no inverter control, use a power factor correctio... More Details >>

FR-PA02 built-in potentiometer

Change Pr.146 (Built-in potentiometer switching) to "0" (built-in frequency setting potentiometer). More Details >>

Can I use it with the single-phase power supply?

You can use the inverter with the single-phase 200 V power supply. However, since ripple current flowing through the capacitor increases and the converter an... More Details >>

Can I use it with single-phase 200 V input?

You can use it with the single-phase 200 V input by increasing the speed controller capacity to one-rank higher than the motor capacity. (Output is three-pha... More Details >>

Acquisition of pressure-resistant explosion-proof certification

The test institutes assigned by the Minister of Health, Labour and Welfare (National Institute of Occupational Safety and Health and Technology Institution o... More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>
