Mode selection (J65)
J65 specifies operation when the load amount exceeds that of one specified by J64.
Data for J65
Mode Description
0 Disable The inverter cancels the overload stop function.
1 Decelerate to stop
The inverter decelerate-to-stops the motor by the
specified deceleration time.
2 Coast to a stop
The inverter shuts down the output immediately, and the
motor coast-to-stops.
3 Hit and stop
The inverter decelerates the motor with the torque limit
operation, and is controlling the output current to keep
the hold toque until the run command turned OFF. Make
the mechanical brake turn ON before turning the run
command OFF.
The inverter issues an alarm IOL or IOL2 during the hit
and stop operation.
• Once the overload stop function is activated, the inverter holds it and cannot
accelerate the motor again. To reaccelerate the motor, turn the run command OFF
and ON again.
• If J65 = 3, the inverter ignores the driving toque limit operation already specified.
Operation condition (J66)
J66 specifies the inverter’s operation state to apply the overload stop function.
Note that carefully specify it so as not to induce a malfunction by any setting that is not
needed.
Data for J66 Applicable operation mode
0 Takes effect in the constant speed or deceleration operation mode.
1 Takes effect in the constant speed operation mode.
2
Takes effect in all the operation modes.
Timer (J67)
J67 configures the timer to suppress any activation of the overload stop function by any
unexpected momentary load fluctuation.
If an activation condition of the overload stop function is taken for the time specified by the
timer J67, the inverter activate it in case of J65 = 1 or 2.
If J65 = 3, the timer setting is ignored. In this case, the inverter decelerates the moto
instantaneously with the torque limit function so that referring to the timer is to
interfere running of this function.
J68 to J72
Braking Signal (Brake OFF current, Brake OFF frequency, Brake OFF timer,
Brake ON frequency and Brake ON timer)
These function codes are for the brake releasing/turning-on signals of hoisting/elevating
machines.
