CC-Link option

The CC-Link communication can be supported by using option FR-A7NC E kit. More Details >>

Slip compensation

Yes, it is. More Details >>

PU signal

It is not output in the JOG operation mode. More Details >>

Parameter copy

Reading during the operation is possible. However, when writing is performed during the operation, "rE2" (parameter write error) occurs. More Details >>

IPM motor drive

Overshooting of the speed due to the acceleration/deceleration may be the cause. Overshooting is more likely to occur when the load inertia is too high. As a... 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 >>

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 >>

What happens if the supplied reactor and outside box are not used?

Harmonics cannot be suppressed (controlled) correctly and noise cannot be removed. Be sure to connect the supplied reactor and outside box to the inverter. More Details >>

Using existing potentiometer by replacing inverter

It is OK if the resistance value of the speed varying potentiometer's resistance is 2 kΩ.Use the speed varying potentiometers used with the existing inverter... More Details >>

Comparison with E500

The major differences are:- Capacity range- Availability of regenerative brake resistor- Operation of the operation panel- Number of I/O terminals More Details >>
