Monitor indicator

Set Pr.37 (Speed display) to the speed obtained when operating the machine at the frequency set with Pr.505 (Speed setting reference). (For FR-F700/E700/D700... More Details >>

Minimum frequency

If any other frequency is not set, when the start signal is input, the inverter starts acceleration from 0.5 Hz set with Pr.13 (Starting frequency) up to 3 H... More Details >>

Multi-speed setting

Priorities are: Low speed (RL) > Middle speed (RM) > High speed (RH).For example, if the low speed (RL) and middle speed (RM) signals are input simulta... More Details >>

Adjustment of analog gain

Use Pr.903 (Frequency setting voltage gain) for setting the FR-E500. For the 700 series, use Pr.125 (Terminal 2 frequency setting gain frequency) and Pr.C4 (... More Details >>

Terminal FM meter connection

Check the connection with the meter.If the terminal FM is connected to the positive terminal and the terminal SD is connected to the negative terminal of the... 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 >>

Proportional band of multiple inverters

By importing the operation frequency from the AM terminal (analog output) of the first inverter to the FR-FH (ratio setter), the operation command which is p... More Details >>

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 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 >>
