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 >>

Imbalanced input and output side power supplies

1. In general, the input power of the inverter is always larger than the output power because the inverter loss is added to the motor loss. 2. In both of cas... More Details >>

Amount of heat generated

The following amount of heat is generated under the 100% load. (The same amount for both the 200 V and 400 V classes. The amount of heat generated by the bui... 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 >>

Can the FR-DU01 be used?

Yes. (However, you need to use the parameter unit connection cable FR-CBL (option).) More Details >>

Difference from general-purpose inverter

While the inverter uses open-loop (V/F) control, it uses semi-closed loop vector control (constant current control). This enables output of stable torque esp... More Details >>

Auto tuning

Vector control performs high-accuracy calculation using the motor constant. Therefore, to perform vector control operation, the inverter must recognize the m... More Details >>

Stop-on-contact control

Set Pr.270 (Stop-on-contact control) to "1".Set Pr.184 (RES terminal function selection) to "3" to choose the RT signal function.When the terminals RL and RT... More Details >>

FR-E700

Install the DIN rail attachment to each inverter.The optional FR-A7NC is built in the inverter and does not influence installation of the inverter. More Details >>

When motor current is large

If the parameters related to the output voltage are not changed from the initial setting, it is unlikely that the output current at 55 Hz and 60 Hz is double... More Details >>
