Rotation speed display

It is not switched. The frequency at the fault saved in the faults history is always displayed in frequency [Hz]. More Details >>

Frequency command

Since the initial value of Pr.13 (Starting frequency) is 0.5 Hz, the operation does not start unless 0.5 Hz or higher frequency is set. When 0.49 Hz is set i... More Details >>

PU operation

1. Yes. 2. Set Pr.17 to "2". 　3. If the start signal is ON, the operation continues even the emergency stop is OFF. More Details >>

Output side earth (ground) fault overcurrent protection

1. How much is the sensitivity current? When the sum of the three-phase output current of the inverter reaches approximately 70% of the inverter rated curren... More Details >>

Terminal

Signals input from the terminal 4 are not enabled if the terminal AU is not ON. For an inverter without the terminal AU, assign the AU function to an unused ... More Details >>

Connecting ammeter to output side

Yes. Use a moving-iron type ammeter. However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the inter... More Details >>

Switching between external operation and NET operation

You can monitor the fault output in both NET operation and external operation. More Details >>

Auto tuning

If "1" is not shown on the frequency monitor, some of the parameters necessary for auto tuning may not be set correctly.Set rated motor current of Pr.81 (Num... More Details >>

Monitor indicator

Press the "SET" key once while the output frequency is monitored.The unit indicator LED changes from "Hz" to "A" and the monitor display changes to the current. More Details >>

Frequency setting

Set Pr.79 (Operation mode) to "3".When a signal is input to the terminal RL, the inverter starts operating at the frequency set with Pr.6 (Multi-speed settin... More Details >>
