Torque Detection
L6-01 04A1
Torque Detection
Selection 1
Load Detection
Determines the drive's response to an overtorque/undertorque condition.
Overtorque and Undertorque are determined by the settings in parameters
L6-02 and L6-03.
0: Disabled
1: OL@SpdAgree - Alm (Overtorque Detection only active during Speed
Agree and Operation continues after detection)
2: OL At RUN - Alm (Overtorque Detection is always active and operation
continues after detection)
3: OL@SpdAgree - Flt (Overtorque Detection only active during Speed
Agree and drive output will shut down on an OL3 fault.)
4: OL At RUN - Flt (Overtorque Detection is always active and drive
output will shut down on an OL3 fault.)
5: LL@SpdAgree - Alm (Undertorque Detection is only active during
Speed Agree and operation continues after detection.)
6: LL at RUN - Alm (Undertorque Detection is always active and
operation continues after detection.)
7: LL @ SpdAgree - Flt (Undertorque Detection only active during Speed
Agree and drive output will shut down on an OL3 fault.)
8: LL At RUN - Flt (Undertorque Detection is always active and drive
output will shut down on an OL3 fault.)
