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 >>

Motor specifications setting

Yes.Set Pr.19 (Base frequency voltage) to "200 V".200 V output will be obtained during 60 Hz operation. More Details >>

Switching between PU and NET operations

Even after setting Pr.340 to "10", the change is reflected after resetting the power supply.Perform the power reset.Since changes to the communication parame... More Details >>

Transistor output module of the programmable controller

Check if signals that are ON when the programmable controller's transistor output starts are always ON. More Details >>

Surge voltage of 400 V motor

When the wire between the 400 V inverter and motor is long (20 m or longer), surge voltage occurs momentarily. This voltage is as two or more times as the DC... More Details >>

RS-485 communication

Blinking of the "RUN" LED on the panel suggests that the frequency command may not be input. Create a frequency setting data as for the forward rotation comm... 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 >>

Parameter setting

Change Pr.79 (Operation mode) to "3" (Combined operation mode) and short-circuit the external terminals STF and SD (or STR and SD for reverse rotation). More Details >>

Frequency setting signal

Calibrate C6 (Pr.904) (Terminal 4 frequency setting bias frequency) and C7 (Pr.905) (Terminal 4 frequency setting gain frequency). If the situation does not ... More Details >>
