Operation frequency

I cannot answer clearly because the load is unknown. The operation cycle of operating for 10 seconds and stopping for 10 seconds is OK, but it is questionabl... 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 >>

Difference between use with A100 and other types

Similarly to the FR-A200 and A500, four or more filters should be used also for the FR-A100. 　In short, it is OK if the wire penetrates the filter four times... More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Durability in multi-speed setting

1. You can set the minimum time by setting the acceleration/deceleration time and acceleration/deceleration reference frequency. 2. No problem with the termi... More Details >>

Current value monitor

The current value can be displayed on the operation panel without regard to the setting of monitor-related parameters. As the current value remains 0 A, the ... More Details >>

Priority of multi-speed setting and frequency setting signals

For frequency setting, multi-speed setting is prioritized over current input. Therefore, when the multi-speed signal is input, the inverter switch to multi-s... More Details >>

Comparison of the speed change rate

Speed fluctuation ratio differs depending on the control method as follows. - V/F control?????????2 to 5% (At the encoder feedback: 0.02%)- General-purpose m... More Details >>

RS-485 communication

It is available since June, 2007. The model is FR-E7TR. More Details >>

Specifications

It can be driven by connecting single-phase 200 V to the terminals R and S. In this case, the load current must be one-third or less of the inverter rated cu... More Details >>
