Name Description
Select the control method for the
torque limit during acceleration
and deceleration.
0: Proportional control (integral
control during constant speed)
1: Integral control
Usually, this constant does not
need to be set.
For applications in which the
torque limit will be reached during
acceleration and deceleration,
torque control can be given priority
by selecting integral control.
When the torque is limited, the
acceleration and deceleration times
may increase or the motor speed
may not agree with the speed refer-
ence value.
Name Description
0: Disabled (no overheating
protection)
1: Enabled (overheating
protection)
Sets the detection tempera-
ture for the Inverter overheat
detection pre-alarm in °C.
The pre-alarm detects when
the cooling fin temperature
reaches the set value.
Sets the operation for when
the Inverter overheat pre-
alarm goes ON.
0: Decelerate to stop in
deceleration time C1-02.
1: Coast to stop
2: Fast stop in fast-stop time
C1-09.
3: Continue operation
(Monitor display only.)
A fault will be given in set-
ting 0 to 2 and a minor fault
will be given in setting 3.
