4. Operation Using I/O Signals
Warning: Since a servo motor is applied as the driving motor, the system performs the excitation phase
detection in the first servo ON process after the power is turned ON.
Therefore, it is necessary that the actuator is free for operation when the servo is turned ON.
It may disturb the excitation pole detection work properly and may cause such problems as an
abnormal operation or the excitation detection error if the slider or the rod is touching the mechanical
end or the work piece is interfering with the surrounding devices.
In such a case, move the actuator by hand to a position where it can be operated freely.
If the unit is equipped with a brake, it is necessary to release the brake manually by putting the brake
release switch ON. Be careful, the slide or rod may drop due to the payload on the actuator. Be sure
to avoid any damage or injuries from the load moving.
If the actuator cannot be moved by hand, there is an option to change Parameter No.28 (Excitation
Pole Signal Detection Direction) setting. However, please contact us in advance if you desire to do so.
