Manual contactor on output side of drive unit

The low-voltage manual contactor is intended to prevent electric shock during inspection and maintenance of the drive unit.The MELIPM series motor is a synch... More Details >>

0 Hz output of inverter

When the command frequency is 0 Hz, the inverter does not generate output and the voltage is 0 V. More Details >>

Built-in regenerative resistor

For both the 200 V and 400 V classes have the built-in regenerative resistor for 0.4 K to 7.5 K.The permissible power is as follows:Capacity: Short-time perm... More Details >>

Two-rank up maximum short-time torque

It is not possible to generate torque larger than the maximum possible torque of the motor by increasing the inverter's capacity.Even when the inverter is up... More Details >>

Installing parameter unit outside control panel

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

Winding control

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... More Details >>

Frequency display deviation

If you are using an external VR, influence by noise is probable.Setting Pr.74 (Input filter time constant) to a higher value stabilizes the frequency command... More Details >>

Vector inverter option

Just by adding this option, encoder pulses connected to the inverter or option are output.You can also divide the pulse train output. More Details >>

FR-BSF01 wiring

The filtering effect is higher as the cable is wound more.However, if the cable is wound more than 4T on the inverter output side, since the inverter's outpu... More Details >>

Can I set the FR-F series parameters?

The FREQROL-F500 series has been already supported by the setup software released since February 2000. More Details >>
