L6-01, L6-04: Torque Detection Selection 1, 2
The torque detection function is triggered when the current or torque exceeds the levels set in L6-02 and L6-05 for longer
than the time set in L6-03 and L6-06. L6-01 and L6-04 select the conditions for detection and the operation that follows.
Setting 0: Disabled
Setting 1: oL3, oL4 at Speed Agree - Alarm
Overtorque 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 an oL3/oL4 alarm is triggered.
Setting 2: oL3, oL4 at Run - Alarm
Overtorque detection works as long as the Run command is active. The operation continues after detection and an oL3 or
oL4 alarm is triggered.
Setting 3: oL3, oL4 at Speed Agree - Fault
Overtorque 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 an oL3 or oL4 fault is triggered.
Setting 4: oL3, oL4 at Run - Fault
Overtorque detection works as long as a Run command is active. Operation stops and an oL3 or 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 or UL4 alarm is triggered.
Setting 6: UL3, UL4 at Run - Alarm
Undertorque detection works as long as the Run command is active. The operation continues after detection and a UL3 or
UL4 alarm is triggered.
Setting 7: UL3, UL4 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 UL3 or UL4 fault is triggered.
Setting 8: UL3, UL4 at Run - Fault
Undertorque detection works as long as a Run command is active. Operation stops and a UL3 or UL4 fault is triggered.

L6-02, L6-05: Torque Detection Level 1, 2
These parameters set the detection levels for the torque detection functions 1 and 2. The setting for torque detection is set
as a percentage of either the drive rated current or of the motor rated torque, depending on the control mode. In V/f
Control, V/f with PG Control, and OLV/PM, L6-02 and L6-05 are set as a percentage of the drive rated current. In all
other control modes (OLV, CLV, AOLV/PM) torque detection is set as a percentage of the motor rated torque.
Note: The torque detection level 1 (L6-02) can also be supplied by an analog input terminal set to H3-
††
= 7. Here, the analog value
has priority and the setting in L6-02 is disregarded. Torque detection level 2 (L6-05) cannot be set by an analog input.
n
L6-03, L6-06: Torque Detection Time 1, 2
These parameters determine the time required to trigger an alarm or fault after exceeding the levels in L6-02 and L6-05.
