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 >>

Using shielded wires for frequency meter connection

Connect the shield to the terminal SD. 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 >>

Frequency display

When Advanced magnetic flux vector control (Pr.80, 81) is used, the machine speed constant is controlled. The inverter calculates the motor slip and compensa... More Details >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

EMC countermeasure

To conform to the EMC Directive when exporting to an EU country, install the filter that conforms to the EMC Directive on the inverter, and take measures acc... More Details >>

Rotation speed setting

1. The inverter display is based on the frequency, and the speed and moving speed are displayed by converting the frequency into the corresponding value. The... More Details >>

Countermeasure against the fault occurrence

When a CC-Link communication fault occurs, the option error (OP3) occurs on the inverter and the output is shut off, and the motor starts coasting. When usin... 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 >>

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 >>
