Parameter setting for FR-E500

General-purpose magnetic flux vector control is effective at low speed under a heavy load.To shorten the acceleration time, use Pr.44 to set the second accel... More Details >>

Installing frequency setting potentiometer

When you are inputting analog signals, install the potentiometer within 30 m from the inverter. 　(Refer to "Precaution on Selection and Operation" on the cat... More Details >>

Switching from star-delta operation

It is probable that the torque is insufficient because the load characteristics and inverter output characteristics do not match and the output current value... More Details >>

Winding control

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... More Details >>

Speed precision of Advanced magnetic flux vector control

The speed precision for each model is as follows:FR-K440 with PG: 1% or less of the maximum speed (3500 rpm)FR-A540 without PG (Advanced flux vector): 1% or ... More Details >>

Rated capacity related to harmonic suppression guidelines

The usual inverter input current is determined not by the inverter capacity but by the motor capacity (motor load).Therefore, the input side capacity is not ... More Details >>

Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. More Details >>

Power supply phase sequence

No problem.The inverter converts AC power into DC power and then into AC (PWM) power output again. Therefore, it is not influenced by the power supply phase ... More Details >>
