(5) Centering and securing the motor unit
Loosen the motor affixing screws you have tightened only loosely in an earlier step, move the slider back and
forth by hand for three to four cycles (over as long an operation stroke as possible) and eventually move the
slider to near the mechanical end on the motor side and find a position at which the motor vibration becomes
the smallest. Affix the motor unit in the motor housing at this position.
(Note) If the actuator is equipped with a brake, connect the encoder cable of the motor unit to the controller
using the extension cables (motor and encoder cables), and apply power to the controller. Then
release the brake and move the slider.
For safety reasons, after securing the motor unit, deactivate the brake release, turn off the power to
the controller and disconnect the cable connectors from the motor unit.
