4. Operation Using I/O Signals
Warning: The excited pole phase is detected when the servo is turned on for the first time after the power has
been turned on, or before an absolute reset is performed following the connection of a simple
absolute unit. The actuator normally moves by approx. 0.5 to 2 mm due to this detection operation,
although the specific distance will vary depending on the ball screw lead.
(On rare occasions where the actuator position at which the power is turned on is not ideal, the
actuator may move by around one half the ball screw lead.)
If the power is turned on when the actuator is positioned near a mechanical end, the detection
operation may cause the actuator to contact the mechanical end and reverse.
Pay due attention not to cause the work or hand to contact any surrounding object and sustain
damage as a result.
