Homing Motors
Homing the motor moves the actuator to the home limit switch and resets the internal
position counter to zero. The limit switch provides a fixed datum that can be found
after the system has been powered up.

1) Click the ‘Home’ button. Notice that the led in the button lights to indicate that
homing is in progress and the displayed position for both channels counts down
to 000.000, i.e the home position.
Note. Homing can also be performed by holding down both front panel buttons for
around 2 seconds.
Note. After homing, shaft relaxation may cause a small position offset to be
displayed. This relates only to one or two encoder counts and is not significant in
terms of ‘real wor‘ld’ positioning.
2) When homing is complete, the ‘Homed’ LED is lit as shown above.
See Appendix D, Section D.2.2. for background information on the home position.
