E．OV2 error

The regenerative overvoltage shutoff protective function is provided since the terminal voltage of the internal capacitor of the inverter can rise abnormally... More Details >>

Switching between external operation and NET operation

You can switch between external operation and NET operation by turning ON/OFF the terminal X66 (RM). You can switch while Pr.79 (Operation mode) is set to "6... More Details >>

Maximum frequency

If you try to change a parameter in other than the PU operation mode, the mode specification error "Er4" may occur.Set the parameters in the PU operation mod... More Details >>

Reverse rotation prevention selection

Yes, it does. When the inverter is coasting in the reverse direction, it starts in the reverse direction and switches to the forward rotation after a deceler... More Details >>

Operation mode setting

Rapid blinking of the RUN LED indicates that the frequency setting command has not been input or the output stop signal has been input.Since Pr.79 is set to ... More Details >>

Frequency setting

If Pr.79 (Operation mode) is set to "0" (PU/EXT switching mode), press the PU/EXT button on the operation panel to turn on the PU LED.Turn the setting dial t... More Details >>

Instruction manual

For the Instruction Manual "Applied", fill in the request sheet which is included in the last part of the Instruction Manual "Basic", and fax it to the speci... More Details >>

Frequency setting

The parameters used when the terminal 4 is used are C5, C6, 126, and C7.Set Pr.C5 (Terminal 4 frequency setting bias frequency) while feeding a current signa... More Details >>

Input phase loss

Check if the input side voltage is equally applied to all three phases. The S phase voltage may be low because the input current flows when the voltage of th... More Details >>

Brake resistor

Use two resistors for the high-duty brake resistor FR-ABR-15K. (Connect two resistors of 18 ? in parallel.) More Details >>
