Changing Overtorque and Undertorque Detection Levels Using an Ana-
log Input
If you set constant H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-
function Analog Input Terminal A3 Function Selection) to 7 (overtorque/undertorque detection level), you can
change the overtorque/undertorque detection level.
If you change the overtorque/undertorque detection level using the multi-function analog input, only over-
torque/undertorque detection level 1 will be enabled.
The following diagram shows the overtorque/undertorque detection level using an analog input.
