 Operation Mode (J66)
J66 specifies the inverter’s operation condition under which
the overload stop function is activated.
Carefully make this setting so as not to activate the
overload stop function when it is not necessary.

0
Enabled during constant speed
and deceleration time.
1
Enabled during constant speed
2
Enabled always
 Timer (J67)
Apply the timer (J67) to prevent the start of the overload stop function due to the instantaneous, unintended load
fluctuation. The overload stop function is activated when the operation condition has continued for specified timer
J67 (if J65 = 1, 2).
If J65 = 3, the timer time will be the time until the stopper contact function is enabled after switching to J66 operation
mode. Set at such times as when waiting time is necessary until the stopper contact function is enabled after the
motor reaches a constant speed.
 Enable overload stop “OLS” ( Function codes E01 to E09, data = 46)
Turning this terminal command ON enables the overload stop function; turning it OFF disables the function. If “OLS”
is not assigned to any terminal, the overload stop function is always valid. Overload stop is not performed when
OFF. By turning OFF the “OLS” signal when the motor is stopped due to an overload stop to disable overload stop,
the motor will restart, and therefore caution is advised.
