Undertorque detection is active when the Run command is active. The drive continues to run
after an Ut1 (Undertorque Detection 1) alarm is triggered.
7 : Undertorque Fault at Speed Agree
Undertorque detection is active only when the output frequency is the same as the frequency
command. No detection during acceleration or deceleration. The drive stops operation after
an Ut1 (Undertorque Detection 1) fault is triggered.
8 : Undertorque Fault at Run
Undertorque detection is active when the Run command is active. The drive stops operation
after an Ut1 (Overtorque Detection 1) fault is triggered.

P6-01 Overtorque/ Undertorque Detection Level 1
Sets the level for overtorque/undertorque detection
Overtorque/ undertorque detection is set as a percentage of the drive rated output current in
Open-Loop V/F Control, Closed-Loop V/F Control, and PM Open-Loop Vector Control control
methods. Overtorque/ undertorque detection is set as a percentage of the motor rated torque
in Open-Loop Vector Control, Closed-Loop Vector Control, and PM Closed-Loop Vector
Control control methods.
No. Name Setting Range Default
P6-01 Overtorque/ Undertorque Detection Level 1 0 to 300% 150%
Note: This level can be set by the analog input terminal assigned to E3-□□=11. The analog input overrides the
setting in this parameter. However P6-04 (Overtorque/ Undertorque Detection Level 2) cannot be set by the analog
input terminal.

P6-02 Overtorque/ Undertorque Detection Time 1
Sets the time for overtorque/undertorque detection 1.
No. Name Setting Range Default
P6-02 Overtorque/ Undertorque Detection Time 1 0.0 to 10.0 s 0.1 s

P6-06 Mechanical Weakening Detection Operation
Sets the speed range to detect mechanical weakening and the operation when detected.
No. Name Setting Range Default
P6-06 Mechanical Weakening Detection Operation 0 to 8 0
0 : Disabled
1 : Continue Operation if the Speed (Signed) is above P6-07
