Operation panel

No, it cannot be connected to the RS-485 terminal. The 485 terminal supports the Mitsubishi protocol and Modbus-RTU, but it does not support the PU protocol.... More Details >>

PU signal

It is not output in the JOG operation mode. More Details >>

Installing reactor for suppressing harmonics

You can connect multiple inverters to a single reactor. In this case, the load seems to be light from the reactor unless all of the inverters are rotating an... More Details >>

Load current limit of inverter

You can input current from the terminal AM of the inverter to the programmable controller (for A/D conversion) and control the speed with the software of the... More Details >>

Countermeasure against inverter noise

You can attach the following filters to the inverter input side:- Line noise filter (FR-BLF, FR-BSF01)- Radio noise filter (FR-BIF) 　While it is a good idea ... More Details >>

How many inverters can be connected?

Up to 32 units can be connected. (This is because the inverter communication conforms to RS-485.) More Details >>

Short-circuiting frequency setting terminals

You can short-circuit the terminals 10 and 2.If you are considering to perform operation at the maximum frequency, consider using the high-speed command RH o... More Details >>

Surge voltage of 400 V inverter

1. Since the voltage resistance of the standard motor is not improved, it is recommended to use an "insulation-enhanced motor".If you are using an insulation... More Details >>

Using existing potentiometer by replacing inverter

It is OK if the resistance value of the speed varying potentiometer's resistance is 2 kΩ.Use the speed varying potentiometers used with the existing inverter... More Details >>

Inverter 200 V input and 400 V output

We do not have an inverter that directly takes 200 V input and generates 440 V output. Therefore, as you mention, use a 400 V class inverter by boosting the ... More Details >>
