3.1 Home Position Return after Motor Replacement
Example of Check-Point Creation when Replacing U-Axis's
Motor of MH0005F-A00.
• The check-point cannot be created unless each axis moves to
operate. Stated differently, the check-point cannot be created if the
axis does not move due to a failure. It is, therefore, recommended to
create the check-point for each axis under normal operating
conditions.
• Check the home position of the replacing axis. Use the position
screen and move the replacing axis to the 0-pulse position: the home
position, then check the position of the home position mark. Please
execute the adjustment if it is deviated.
The Fig. 3-1 "Preparation before Replacement (Example)"shows the
MH0005F-A00 U-axis replacement as an example.
