Operation with CC-Link

1. By changing RWw1 while RYD is ON, you can change the inverter's frequency.You cannot do this with RYE. You need to turn OFF and then ON RYE each time you ... More Details >>

Brake sequence function

Since the brake sequence function requires Advanced magnetic flux vector control and advanced flux control is applied to 0.4 kW or higher motors, you cannot ... 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 >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... 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 >>

Using shielded wires for frequency meter connection

Connect the shield to the terminal SD. More Details >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>

Driving two motors with different capacities

It is OK to drive motors by switching the electromagnetic contactor on the inverter's output side.It is also OK if the motor capacity is small. However, if t... 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 >>

Fault output contact rating

They are capable of a load of 5 VDC±5% and 10 mA. More Details >>
