Overload Stop Function
This function is used to detect the load condition, and if the state exceeding the Overload Stop Detec-
tion Level (J64) continues for the Overload Stop Detection T
imer (J67) or longer, stop operation is per-
formed by the overload stop function.
Select the stop operation at Overload Stop Mode Selection (J65). If “0: Disable” is selected, the over-
load stop function is disabled.
The overload stop function is enabled only for the 1st control.
Select the operation to detect at Overload Stop Operation Mode (J66).
Select the item to detect at Overload Stop Item Selection (J63).

Turning the OLS terminal ON enables overload stop and turning the terminal OFF disables overload
stop.
Note that if overload stop is disabled by turning OFF the OLS terminal in a state when the inverter has
stopped due to overload stop, the inverter will restart.
Overload Stop Mode Selection (J65)
• Select the stop operation at Overload Stop Mode Selection (J65). If “0: Disable” is selected, the
