Note
•
During the referencing process, the signals CWL and CCWL are unavailable. Once the
process is complete, the signals will act as limits signal again.
•
For the safety purpose, the maximum distance for searching the cam (p2606) and the
maximum distance for searching the zero mark (p2609) must be set.
Follow the steps below to perform referencing with this mode:
1.
Set relevant parameters.
Parameter Range Default Unit Description
p2599 -2147482648 to
2147482647
0 LU Sets the position value for the reference
point coordinate.
p2600 -2147482648 to
2147482647
0 LU Reference point offset
p2604
1)
0 to 1 0 - Sets signal source for start direction of
searching:
•
0: start in positive direction (CW)
•
1: start in negative direction (CCW)

Speed for searching reference point
1)
When p29240= 3, the direction for searching the reference cam must be CCW, that is
p2604=1.
2. Configure the signal SREF and CCWL.
3. Trigger SREF to a rising edge to start referencing.
Note
During the referencing, if SREF is OFF, the referencing stops.
4. If the servo motor reaches the reference point, the signal REFOK (if configured) is output.
5. Switch off the signal SREF, and the referencing finishes successfully.
