L6: Torque Detection
Use L6 parameters to configure overtorque detection.
L6-01
Torque Detection Selection
1
Selects the overtorque/undertorque operation. overtorque
and undertorque are determined by the settings in
parameters L6-02 and L6-03. The multi-function output
settings (H2-= B and 17) are also active if
programmed.
0: Disabled
1: oL3/oL4 at Speed Agree - Alarm (overtorque detection
only active during Speed Agree and operation continues
after detection).
2: oL3/oL4 at RUN - Alarm (overtorque detection is
always active and operation continues after detection).
3: oL3/oL4 at Speed Agree - Fault (overtorque detection
only active during Speed Agree and drive output will shut
down on an oL3/oL4 fault).
4: oL3/oL4 at RUN - Fault (overtorque detection is always
active and drive output will shut down on an oL3/oL4
fault).
5: UL3/UL4 at Speed Agree - Alarm (undertorque
detection is only active during Speed Agree and operation
continues after detection).
6: UL3/UL4 at RUN - Alarm (undertorque detection is
always active and operation continues after detection).
7: UL3/UL4 at Speed Agree - Fault (undertorque detection
only active during Speed Agree and drive output will shut
down on an UL3/UL4 fault).
8: UL3/UL4 at RUN - Fault (undertorque detection is
always active and drive output will shut down on an UL3/
UL4 fault).

<15>
Torque Detection Level 1
Sets the overtorque/undertorque detection level. 100% is
equal to the motor rated current in V/f Control and the
motor rated torque in Open Loop Vector Control.

Torque Detection Time 1
Sets the length of time an overtorque/undertorque
condition must exist before Torque Detection 1 is triggered.

L6-04
Torque Detection Selection
2
Sets the response to an overtorque/undertorque condition.
Overtorque and undertorque are determined by the settings
in parameters L6-05 and L6-06. The multi-function output
settings (H2- = 18 and 19).
0: Disabled
1: oL4 at Speed Agree - Alarm (overtorque Detection only
active during Speed Agree and Operation continues after
detection).
2: oL4 at RUN - Alarm (overtorque Detection is always
active and operation continues after detection).
3: oL4 at Speed Agree - Fault (overtorque Detection only
active during Speed Agree and drive output will shut down
on an oL4 fault).
4: oL4 at RUN - Fault (overtorque Detection is always
active and drive output will shut down on an oL4 fault).
5: UL4 at Speed Agree - Alarm (undertorque Detection is
only active during Speed Agree and operation continues
after detection).
6: UL4 at RUN - Alarm (undertorque Detection is always
active and operation continues after detection).
7: UL4 at Speed Agree - Fault (undertorque Detection only
active during Speed Agree and drive output will shut down
on an oL4 fault).
8: UL4 at RUN - Fault (undertorque Detection is always
active and drive output will shut down on an oL4 fault).
