Can a brake resistor or brake unit be connected?

You can connect them to the FR-A024 inverter 0.4 to 3.7K. (You cannot connect them to 0.1K and 0.2K.)Available brake resistor options include the FR-ABR high... More Details >>

Regenerative power flow

If all inverters are in regenerative operation, the regenerative power is regenerated to the power supply. If one of the inverters is power driving, the rege... More Details >>

Pre-excitation, zero-speed control, and servo lock

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediately. There are two methods for this p... More Details >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>

Speed does not exceed 46 Hz

Since the inverter displayed "0.00" instead of an error when the inverter speed dropped to 0 Hz and stopped by holding the winding machine by hand, it is con... More Details >>

Inverter operation against power supply voltage drop

Depending on the load current, undervoltage protection (UVT) or instantaneous power failure protection (IPF) is triggered to shut off the inverter output, an... More Details >>

FR-A5CN

When the heat sink is outside, since the heat sink and fan are not waterproof, you need to enclose them so that they are not exposed to the spray of water. More Details >>

FR-BIF

It is available. Insulate the raised wiring of T-phase. More Details >>

Europe EMC Directive compliance

By turning ON the connector of the built-in filter, the inverter can be compliant with EMC Directive (EN 61800-3 2nd Environment C3) alone. More Details >>
