14.4.6.1.3 Search Home Mode:=1 (P2P HOME, Forward DOG Switch & check PG-INDEX)
Under this mode, when an external signal triggers the digital input DIx(32), the motion controller will
execute the following procedures in order to find the home position:
Step1:the servomotor start rotates in Forward direction
Step2::the servomotor stops when DIx(33)=1, meaning the DOG switch ON
Step3::the servomotor rotates in Reverser direction away from the DOG switch
Step4::When the DOG switch is OFF again, DIx(33)=0, the servomotor continues to rotate in Reverser
direction checking the PG-Index of the motor encoder.
Step5::after the PG-Index is checked, the servomotor stops.
Step6::for the final step, the controller executes an P2P function commands the servomotor move to the
desired shift position (with respect to the PG-index point. In the mean time, DOx(32)=1, to indicate
the end of the Home-Search function.
