Functions available when using inverter on CC-Link

You can use the regular terminal block wire functions during CC-Link operation. 　Set Pr.338 (Operation command source) and Pr.339 (Speed command source) to e... More Details >>

Installing parameter unit outside control panel

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Multi-speed operation

Use the first contact (relay) for the forward (or reverse) rotation between the terminals STF and SD. Use the second contact (relay) for the high-speed comma... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>
