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.)
