[Overview of Replacement]
1) Move the rod to a position where Z phase turns on (home position) (2 mm from the mechanical end). In this
position, replace the motor.
2) Perform homing using a PC or teaching pendant and check for deviation from the initial home position.
If there is a deviation, adjust the home offset if you are using an SCON controller. If you are using an SSEL or
X-SEL controller, adjust the home preset.
