Setting 4: oL3/oL4 at Run - Fault
Overtorque detection works whenever a Run command is active. The operation is stopped and an oL3/oL4 fault is triggered.
Setting 5: UL3/UL4 at Speed Agree - Alarm
Undertorque detection is active only when the output speed is equal to the frequency reference, i.e., no detection during
acceleration and deceleration. The operation continues after detection and a UL3/UL4 alarm is triggered.
Setting 6: oL5/UL5 at Run - Alarm
Undertorque detection works whenever a Run command is active. The operation continues after detection and an oL5/UL5
alarm is triggered.
Setting 7: UL5 at Speed Agree - Fault
Undertorque detection is active only when the output speed is equal to the frequency reference, i.e., no detection during
acceleration and deceleration. The operation is stopped and a UL5 fault is triggered.
Setting 8: oL3/oL4 at Run - Fault
Undertorque detection works whenever a Run command is active. The operation is stopped and an oL3/oL4 fault is triggered.
Setting 9: UL6 Alarm at Speed Agree
Setting 10: UL6 Alarm during Run
Setting 11: UL6 Fault at Speed Agree
Setting 12: UL6 Fault during Run

Note:
1.
The torque detection level 1 (L6-02) can also be supplied by an analog input set to H3-02/10 = 7. In this case the analog value has priority
and the setting L6-02 is disregarded. Torque detection level 2 (L6-05) cannot be set by an analog input.
2.
The detection levels for overtorque and undertorque are set as a percentage of the drive rated current when using V/f Control or Open
Loop Vector Control. When using Closed Loop Vector Control, the drive sets torque detection as a percentage of the motor rated current.

L6-03/L6-06: Torque Detection Time 1/2
