CC-Link

You can check the fault records with Pr.544 (CC-Link extended setting) set to "12" for double setting.Set H74 for the instruction code and turn ON RYF. More Details >>

Comparison of noise between FR-A100 and FR-A100E

The setting ranges of the carrier frequency are:- FR-A100: 2 kHz to 14.5 kHz- FR-A100EXCELLENT: 0.7 kHz to 14.5 kHzThe range of the FR-A100EXCELLENT is exten... 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 >>

Compatibility with Y-△ motor and others

1. You can connect them using △ connection. 2. No problem with connecting four Y-△ motors. (Connect all four motors using △ connection.) (Note that the inver... More Details >>

Details of zero current detection

1. The inverter also monitors the output current during DC injection brake operation in addition to normal operation. Therefore, zero current detection also ... More Details >>

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 >>

Built-in reactor

The reactor built in the FREQROL-A201 series is intended to stabilize operation of the converter circuit and differs from the FR-BAL. Note that when performi... More Details >>

System environment variable of the Modbus-RTU communication

It decelerates and stops. The operation is the same as the one when the Bit of forward rotation command and reverse rotation command are turned OFF. More Details >>

400 V inverter

No, it does not run. "Err" is displayed when it is operated. Always input the same voltage (400 V) to the main power supply and control power supply. More Details >>

Vector control

"E.OSD" occurs when the rotation speed is not decreased for one second despite the start command (STF, STR) is turned OFF. More Details >>
