CC-Link IE Field Basic

Up to 64 (slave stations). The number of connectable units differs depending on the master station. More Details >>

Relationship between undervoltage warning and instantaneous power failure

When an instantaneous power failure occurs and the inverter's bus voltage drops below the standard value, it outputs an undervoltage warning and stops its ou... More Details >>

Encoder

It is necessary for vector control operation. Use a dedicated motor or a motor with an encoder. If you use another manufacturer's motor, use an encoder capab... More Details >>

Inverter analog output

Since the inverter has only one voltage output (10 VDC) from terminal AM as the analog monitor, use the FR-EPA or FR-EPE option if you need two channels. The... More Details >>

Current value on input side and output side

1. When slight imbalance (approximately 5%) is present with the inverter power supply voltage, the inverter input current can get imbalanced significantly. I... More Details >>

Installing magnetic contactor on input side of inverter

Basically, there is no difference between the A200 and A500. For safer use, from the A500, it is recommended to completely shut off the power supply by turni... More Details >>

FR-A5CN03

Since the heat sink and fan are not waterproof, you need to enclose them so that they are not exposed to the spray of water. If you use the inverter (heat si... More Details >>

12-bit digital input and others

You can switch between PU operation and external operation using the plug-in option "12-bit digital input" card and external contact signals. After setting P... 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 >>

Setting resolution switching

Check the setting value of Pr.37 (Speed display). When the machine speed is set, Pr.811 is disabled. Change the setting to the rotation speed. More Details >>
