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 >>

Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... 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

CC-Link

You can use optional items, such as enclosure surface operation panel FR-PA07 and parameter unit FR-PU07.Use the PU connector of the inverter for connection.... More Details >>

CC-Link

You cannot monitor the running frequency and conveyor speed (machine speed) simultaneously.The inverter does not have a function to output them simultaneously. More Details >>
