Name Description
Default
(Range)
L6-01
(04A1)
Trq Det1 Select
Enables overtorque and undertorque detection and the operation of drives (operation status) after
detection.
0
(0, 1)
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]
.

L6-02 Trq Det1 Level
No.

Name Description
Default

L6-02
(04A2)
Trq Det1 Level
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.
150%
(0 - 300%)
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 .

Trq Det2 Select
Sets the speed range that detects overtorque and undertorque and the operation of drives
(operation status) after detection.
0
(0, 1)
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] .
