Caution: When replacing the motor, handle the replacement motor with due care. The actuator
has been shipped with the encode adjusted to an optimal position, so do not crush the
encoder unit. It may displace the encoder, thus impairing proper actuator operation.
[Overview of Replacement]
1) Move the slider to a position where Z phase turns on (home position) (2 mm from the mechanical end).
Replace the motor in this position.
2) Perform homing using a PC or teaching pendant and check for deviation from the initial home position.
If there is a deviation when the SCON controller is being used, use home return offset distance to
make the adjustments. If the SSEL or the X-SEL controller is being used, use home preset value to
make the adjustments.
