Output frequency monitor value

When running the inverter after auto tuning, the frequency setting value is increased by the amount of the motor slippage, resulting in a higher monitor valu... More Details >>

External thermal overheat

Take the following countermeasure:1. If the thermal trips in low-speed operation, trips can be avoided, depending on the external thermal relay operation cha... 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 >>

Coasting operation of the inverter

To use an inverter using the external contact coast to stop (to shut off the inverter's output), short-circuit the terminals MRS and SD.For CC-Link operation... More Details >>

Relationship between frequency and output torque

The output torque characteristics of the FREQROL-E500 series are shown in the figure below. Figure 1 More Details >>

Changing main speed at analog signal input

To change the running frequency while the frequency command is input to the terminal 2, adjust the parameters in the following steps:1. Change Pr.77 to "2".2... More Details >>

Angular velocity change control

The inverter itself does not have a function to detect the rotation angle and change the velocity accordingly. Therefore, to implement required control, it i... More Details >>

Safety stop function of the FR-D700/FR-E700

It is recommended to install the magnetic contactor on the input side of the inverter for safety. The category 3 can be satisfied without installing it. More Details >>

Built-in PLC function

The error indicates that the parameter setting of the PLC function is not set. It is considered that the PC parameter is not checked when the PC parameter an... More Details >>
