Connection of options

1. As the reactor (FR-HCL) is connected when connecting the FR-HC, do not connect the FR-BAL. 2. The noise filter can be connected to the input side of the F... More Details >>

Which motors can I use with the inverter?

You can use general-purpose three-phase induction motors.You can also use geared motors if the motor itself is an induction motor.Synchronous motors are not ... More Details >>

Switching between high speed and low speed

As you mention, when the inverter is operated only with STF without inputting the speed command signal, the minimum frequency must be set to 10 Hz.However, a... More Details >>

Thermal characteristics of motor

Basically, when the motor temperature goes higher, the motor rotation speed goes lower.The motor rotation speed also changes when the inverter input power su... More Details >>

All parameters returned to initial values

The parameters of the A500 series are stored in the EEPROM.The reason why all parameters returned to the initial values is considered that you may have opera... More Details >>

Already released.Unlike the E520, you need to purchase the optional card FR-E5NC. More Details >>

Consideration on thermal

A motor overheats (the current increases) when the load is heavy.When the electronic thermal O/L relay works, you need to mitigate the load.If the current is... More Details >>

0 Hz output of inverter

When the command frequency is 0 Hz, the inverter does not generate output and the voltage is 0 V. More Details >>

Availability of parameter unit

You cannot use the FR-PU04 with the FR-HC. More Details >>
