The drive detects overtorque if the motor current or output torque is more than the level set in L6-02 [Trq Det1
Level] for the length of time set in L6-03 [Trq Det1 Time]. The drive detects undertorque if the motor current or
output torque is less than the level set in L6-02 for the length the time set in L6-03.
0 : Disabled
1 : Enabled
The behavior is adjusted using parameters L6-50 [Trq Det1 Type], L6-51 [Trq Det1 Action], and L6-52 [Trq Det1
Condition].

Note:
• Set the torque detection level as a percentage of the drive rated output current in all control methods to set the mechanical weakening
detection level.
• You can also use an analog input terminal to supply the torque detection level. To enable this function, set H3-xx = E [AI Function
Select = OvUntrq Level]. If you set L6-02 and H3-x = E, the analog input is most important and the drive disables L6-02.

The drive detects overtorque if the motor current or output torque is more than the level set in L6-05 [Trq Det2
Level] for the length of time set in L6-06 [Trq Det2 Time]. The drive detects undertorque if the motor current or
output torque is less than the level set in L6-05 for the length the time set in L6-06. Adjust the conditions using
parameters L6-53, L6-54, and L6-55 [Trq Det2 Type, Trq Det2 Action, and Trq Det2 Condition].

Configuration Parameter
Detection Criteria
Detection Level
Detection Time
V/f CL-V/f OLV CLV
Enables overtorque and undertorque detection and the operation of drives (operation status) after
detection.
V/f CL-V/f OLV CLV
Sets the detection level for Overtorque/Undertorque Detection 1. In V/f control, drive rated output
current = 100% value. In vector control, motor rated torque = 100% value.
V/f CL-V/f OLV CLV
Sets the detection time for Overtorque/Undertorque Detection 1.
V/f CL-V/f OLV CLV
Sets the speed range that detects overtorque and undertorque and the operation of drives
(operation status) after detection.
V/f CL-V/f OLV CLV
Sets the detection level for Overtorque/Undertorque Detection 2. In V/f control, drive rated output
current = 100% value. In vector control, motor rated torque = 100% value.
