[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.)
