③ Limit Origin (In case of ‘Org Method’= 2)
The machine moves up to the position which the limit sensor is sensed by ‘Org Speed’
& ‘Org Search Speed’parameters, and stops by ‘Org Acc Dec Time’value. The moving
direction complies with as set in ‘Org Dir’.
If there’s no limit sensor on your system, you can set ‘Origin’ by ‘S/W Limit Plus
Value’ and ‘S/W Limit Minus Value’of parameters.
When the limit sensor is detected, the stop method is fixed to
‘Soft Stop’, nt depends on parameter value.
④ Torque Origin (In case of ‘Org Method’= 3 )
The machine moves up to the wall which the pushing torque is reached to ‘Org Torque
Ratio’value. This method can be used without origin sensor and without limit sensor.
If the HW limit sensor is sensed, the motion is stop and the Origin Search OK signal
Remains OFF status.
