[Home Return Offset Distance (SCON) and Home Preset Value (SSEL and X-SEL) Correction Example]
If, after the motor replacement, the home position became deviated by 0.1 mm in the direction of moving away
from the mechanical end.
In this case, to align it with the initial home position when the SCON controller is being used, reduce the home
return offset distance of parameter No. 22 by 0.1 mm. If the SSEL or the X-SEL controller is being used, reduce
the home preset value
of axis-specific parameter No. 12 by 0.1 mm.
(Change from 2 mm to 1.9 mm.)
