• Overtorque detection function selection (n59)
(1) To detect overtorque at accel/decel, set to 3 or 4.
(2) To continue the operation after overtorque detection, set to 1 or 3.
During detection, the operator displays “ ” alarm (blinking).
(3) To halt inverter by a fault at overtorque detection, set to 2 or 4. At detection, the
operator displays “ ” fault (ON).
• Overtorque detection level (n60)
Sets the overtorque detection current level in units of 1%. (Inverter rated current =
100%)
Factory setting: 160%
• Overtorque detection time (n61)
If the time when the motor current exceeds the overtorque detection level (n61),
the overtorque detection function operates.
Factory setting: 0.1sec.

2
Detected during speed agree (fault). Operation stops during
detection.
3
