L6 Torque Detection
The overtorque detection circuit activates when the motor load causes the motor current (or torque) to exceed the
overtorque detection level (L6-02).
L6-01 Overtorque Detection 1 Selection
Activates overtorque detection, and selects whether detection generates an alarm or a fault.
Setting Explanation
Notes:
1.To detect torque during acceleration or deceleration, set to "2" or "4."
2.To continue operation after overtorque detection, set to "1" or "2." During detection, the digital operator dis
plays an "OL3" alarm (blinking).
3.To stop the inverter after an overtorque detection fault, set to "3" or "4." During detection, the digital opera
tor displays an "OL3" fault.
L6-02 Overtorque Detection 1 Level
Sets the overtorque detection level as a percentage of motor rated torque.
Minimum Maximum Description
0 300
L6-03 Overtorque Detection 1 Time
The overtorque detection delay time inserts a delay, between the time motor current (or torque) exceeds the over-
torque detection level (L6-02) and when the overtorque detection function is enabled. The digital operator then dis-
plays "OL3."
Minimum Maximum Description

agree level (when inverter is not accelerating or decelerat-
ing). Continue running after detection (OL3 alarm).
Overtorque detection is enabled always. Continue running

after detection (OL3 alarm).
Overtorque detection is enabled whenever at the speed
