14.3.5 Return to reference point
For return to reference point, the typical motion is shown in the fig 14.5, being different
from the conventional specification especially on the following points.
• After dog detection, motion pauses on the dog. (When the dog is not long enough, you
must take some measures, for example retaining the signal of dog with a ladder.)
• Encoder C phase detection should be done by moving to the opposite direction to the
dog.
(However, if encoder C phase is preceding to the dog, it is possible to specify the direc-
tion with MD34050).
The primary machine data on return to reference point is as follows.
• MD34000 REFP_CAM_IS_ACTIVE (For each axis)
Meaning:
Return to reference point dog setting
Setting value: 0---No dog
1---Dog
Note: For spindles, specify "0" (no dog) for orientation.
