Brake unit selection

Since the FR-A540-0.75K has a brake transistor for resistor regenerative driving inside the inverter, you do not need to use BU. Just remove the jumper from ... More Details >>

Parameter writing via CC-Link

Pr.133 can be written.Since the data code numbers of parameters are duplicate, target parameters are switched by link parameter extended setting.You can acce... More Details >>

External wiring for CC-Link operation

For the combination of the FR-A500 + FR-A5NC, Pr.338 and Pr.339 are used to specify whether the external signals or CC-Link commands are used to set the runn... More Details >>

Concurrent monitoring of running frequency, output voltage, and output current

Add an analog output by the FR-A5AY.Monitor the three output; output AM (0 to 5 (10) V) and optional 4 to 20 mA, and 0 to 5 (10) V. More Details >>

Clutch connection of load

Since a large load is applied to the motor when the electromagnetic clutch turns on, overcurrent may occur if the load is heavy. To ensure that the rated cur... More Details >>

Selection of high-duty brake resistor
