*1 You can also use an analog input terminal to supply the torque detection level. To enable this function, set H3-xx = E [MFAI
Function Select = OvUntrq Level] . If both L6-02 and H3-xx = E are set, the analog input has priority and the setting of L6-02 is
disabled.
You cannot use Overtorque/Undertorque Detection 2 to set the detection level for the analog input terminals.
Note:
In V/f Control, the drive uses the current level (100% of the drive rated output current) to detect overtorque/undertorque. In vector
control, the drive uses the motor torque (100% of the motor rated torque)to detect overtorque/undertorque. When you enable the
mechanical weakening detection function, the overtorque/undertorque detection level for all control modes is the current level (100% of
the drive rated output current).

Time Chart for Detection of Overtorque/Undertorque
Overtorque Detection Time Chart
When you use Overtorque/Undertorque Detection 1, the drive detects overtorque if the motor current or motor
torque is at the detection level set in
L6-02 [Trq Det1 Level] for the time set in L6-03 [Trq Det1 Time] . Parameter
L6-01 [Trq Det1 Select] sets the operation after detection.
When you use Overtorque/Undertorque Detection 2, set L6-04 [Trq Det2 Select] , L6-05 [Trq Det2 Level] , and L6-
06 [Trq Det2 Time] .
Set the terminal that outputs the alarm in H2-01 to H2-03 [MFDO Function Select] .
Figure 12.125 Overtorque Detection Time Chart
Note:
The drive applies a hysteresis of approximately 10% of the drive rated output current or the motor rated torque to the overtorque/
undertorque detection function.
Undertorque Detection Time Chart
When you use Overtorque/Undertorque Detection 1, the drive detects undertorque if the motor current or motor
torque is less than or equal to the detection level set in
L6-02 for the time set in L6-03 . Parameter L6-01 sets the
operation after detection.
When you use Overtorque/Undertorque Detection 2, set the operation in L6-04, L6-05, and L6-06 .
Set the terminal that outputs an alarm in H2-01 to H2-03 .
