Run Command Selection

This section explains the two run command modes of the power regenerative unit. Select the mode according to the application.

Auto Run

Auto run is the mode in which the power regenerative unit detects any increase/decrease of the bus voltage and performs an auto run/stop if the
terminal S2-SC is "closed."
When the DC voltage is less than the voltage set at the auto run/stop level, the RC5 will stop after the preset time value in parameter C8-20 is passed
(default: 1 sec).

Manual Run

Manual run is the mode in which the RC5 starts running when the terminal S1-SC is "closed," and stops one second after S1-SC is "open."
