Long motor wiring

When you use a long wire between the inverter and motor, pay attention to the following: 1. Since the voltage supplied to the motor terminal is reduced due t... More Details >>

Countermeasure against error

The inverter alarm "OV3" occurs when the main circuit DC voltage inside the inverter goes higher than the preset value due to the regenerative power returned... More Details >>

FR-A5CN

When the heat sink is outside, 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. More Details >>

Inverter data cannot be read

It is considered that communication settings between the inverter and personal computer do not match. Check if settings such as communication rate and stop b... More Details >>

Noise from motor at low speed

It is considered to be caused by inverter PWM control. It can be suppressed by raising the PWM carrier frequency (Pr.72), but the entire noise and leakage cu... More Details >>

Thermal protection

Providing thermal protection is better for your safety. When the brake transistor explodes, the brake transistor alarm (E.BE) is output. Consider a counterme... More Details >>

Countermeasures when input power supply is turned off upon equipment fault

1. When the inverter power supply is turned OFF, the inverter is disconnected from the CC-Link network. However, since the CC-Link master station has the aut... More Details >>
