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 [Torque Detection Level 1] for the time set in L6-03 [Torque Detection Time 1]. Parameter L6-01 [Torque Detection Selection 1] sets the operation after detection.
When you use Overtorque/Undertorque Detection 2, set L6-04 [Torque Detection Selection 2], L6-05 [Torque Detection Level 2], and L6-06 [Torque Detection Time 2].
Set the terminal that outputs the alarm in H2-01 to H2-04 [MFDO Function Select].

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 H2-04.

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.
