"Err" displayed at power-ON

This error is displayed when the inverter and operation panel FR-PU04 cannot communicate with each other correctly or the reset signal remains ON. Therefore,... 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 >>

CC-Link

Although you specify the FR-V200 and others as the inverter models, CC-Link is currently supported by the FR-A500 and FR-E500. The FR-V200E does not support ... More Details >>

Connection with personal computer

Connection method for the A500 and E500 is shown in the figure below. The figure is given in an Excel file. Figure 1 More Details >>

Countermeasure against oil mist

1. You cannot use the inverter in an environment where it is exposed to oil mist. 　You need to enclose the inverter in an enclosure and then install the encl... 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 >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>

Inverter general matters

1. To perform emergency stop, it is recommended to have the motor coast and stop it using a mechanical brake.In this case, the output stop (MRS) signal is in... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>

Rotation speed setting

1. The inverter display is based on the frequency, and the speed and moving speed are displayed by converting the frequency into the corresponding value. The... More Details >>
