FR-A800-E

There are some restrictions compared to the FR-A800 (RS-485 communication type). For example, the FR-A8TR is unavailable, and only two option connectors are ... More Details >>

FR-A800

No, they do not. Pr.72 is invalid at the offline auto tuning. It is also invalid when the motor rotates with Pr.96 = 101. More Details >>

FR-A800-R2R

The X114 signal is for switching the control to the dancer control or tension sensorless torque control. The signal input becomes invalid during operation be... More Details >>

Inverter

You can use the Hioki Memory HiCorder and clamp-on AC/DC high tester.You can observe the inverter's frequency in one of the following two methods:1. Attach t... More Details >>

Switching between high speed and low speed

As you mention, when the inverter is operated only with STF without inputting the speed command signal, the minimum frequency must be set to 10 Hz.However, a... More Details >>

Reset command during operation

The reset signal does not damage the inverter.It seems that the inverter went faulty due to other reasons.Mitsubishi Electric FA Center can inspect the inver... 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 >>

Motor retention at 0 Hz

The inverter does not have a function to limit the current at 0 Hz.Although it has the DC injection brake, it is intended to improve the braking capability b... More Details >>

Speed adjustment of multiple inverters using variable resistor

You can connect up to three inverters in parallel to an external variable resistor. Refer to the figure below for a connection example. By setting parameters... More Details >>

FR-PA07

Basically it is not possible due to the operation command source.However, if Pr.77 (Parameter write selection) is set to "2", you can use both the FR-PA07 an... More Details >>
