Brake unit

1. No parameter setting is required.2. Do not remove the jumpers. More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

Using a higher grade power factor improving reactor

Using a reactor under a load lighter than the rated capacity slightly spoils its effect in improving the power factor.Therefore, you should use a reactor wit... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... 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 >>

Regenerative brake resistor

The brake resistor is not built in the inverter. Purchase the optional resistor and connect it to the inverter.Inverter only (without resistor)Continuous reg... More Details >>

Control method

1. Can I set the frequency by the external potentiometer when multi-speed signal is 0 (nothing is input)?-> It is possible by using the external operation... More Details >>

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 >>

Availability of parameter unit

You cannot use the FR-PU04 with the FR-HC. More Details >>

Installation method of AM-5 terminal ammeter

The AM-5 output is 0 to 10 VDC voltage output.Therefore, you need to install a voltmeter.Also, since the inverter output current is displayed, the scale of t... More Details >>
