For operation selection (J65 = 1, 2)
If deceleration stop (J65 = 1) is set when output torque or output current has continued for the de-
tection timer (J67) or longer set with the Overload Stop Detection Level (J64), a deceleration stop
is performed at the selected deceleration time.
When free run stop (J65 = 2) is set, inverter immediately shuts down and the motor enters the free-
run state.

For operation selection (J65 = 3)
• PI control is started by the set values of Overload Stop Function P gain (P) (J90) and Overload
Stop Function Integral time (J91) when the Overload Stop Detection Level (J64) is reached. Tor-
que is controlled by PI control so that the Overload Stop Detection Level (J64) is maintained.
When the Frequency Lower Limit (F16/E118) is reached, control is switched to current control.
Overload Stop Item Selection (J63) is not related to this setting.
