L6-02 Torque Detection
Level 1
(04A2)
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 = 7 [MFAI Function
Select = Overtorque/Undertorque DetectLvl]. If you set L6-02 and H3-x = 7, the analog input is most important and the drive disables
L6-02.

L6-04 Torque Detection
Selection 2
(04A4)
The drive detects overtorque if the motor current or output torque is more than the level set in L6-05 [Torque
Detection Level 2] for the length of time set in L6-06 [Torque Detection Time 2]. 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.
0 : Disabled
The drive will not detect overtorque or undertorque.
1 : oL @ Speed Agree - Alarm only
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs an oL4 [Overtorque Detection 2] and operation
continues.
2 : oL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 and
operation continues.
3 : oL @ Speed Agree - Fault
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs an oL4 [Overtorque Detection 2] and operation stops.
4 : oL @ RUN - Fault
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 and
operation stops.
5 : UL @ Speed Agree - Alarm only
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL4 [Undertorque Detection 2] and operation
continues.
6 : UL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL4 and
operation continues.
7 : UL @ Speed Agree - Fault
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL4 and operation stops.

V/f CL-V/f OLV CLV AOLV
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 AOLV
Sets the detection time for Overtorque/Undertorque Detection 1.
V/f CL-V/f OLV CLV AOLV
Sets the speed range that detects overtorque and undertorque and the
operation of drives (operation status) after detection.
