Use Parameter home return offset distance (SCON) or home
preset value (SSEL and X-SEL) to specify the settings
(The values displayed above are factory default settings).

� Replacement motor � Coupling (with screws)
� Allen wrenches � Phillips screwdriver
� Scale � Oil-based marker pen
� Grease

• PC or teaching pendant
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.
