• Overtorque detection function selection 1 (n096)
(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 “OL3” alarm (blinking).
(3) To halt the inverter by a fault at overtorque detection, set to 2 or 4. At
detection, the operator displays “OL3” fault (ON).
• Overtorque detection level (n098)
Sets the overtorque detection current level in units of 1%. (Inverter rated
current = 100%) When detection by torque is selected, motor rated torque
becomes 100%.
Factory setting: 160%
• Overtorque detection time (n099)
If the time when motor current exceeds the overtorque detection level
(n098) is longer than overtorque detection time (n099), the overtorque
detection function operates.
Factory setting : 0.1sec.
• Overtorque/Undertorque detection function selection 2 (n097)
When vector control mode is selected, it is possible to select whether
overtorque/undertorque detection is performed by output current or output
torque.
When V/f control mode is selected, the n097 setting becomes invalid, and
overtorque/undertorque is detected by output current.
