NOTE

To home the motor in the X axis, the motor drives in the reverse direction until it sees

the home sensor. The motor changes direction to drive the vane out of the home sensor.

On receipt of the next encoder index pulse the motor stops.

Used in conjunction with the respec-

tive encoder index pulses to provide

accurate repeatable home position-

ing in the camera X axis.

Dig IN 15

Used in conjunction with the respec-

tive encoder index pulses to provide

accurate repeatable home position-

ing in the camera Y axis.

Board Stop In Through

Beam Opto

NextMove X2

Dig IN 23

Detects when the board stop is low-

ered and is used to prevent a colli-

sion with the rails should the return

spring fail whilst the camera is trav-

eling over them.

Opto

NextMove X2

Dig IN 22

Detects a board present at the board

stop during board load. Its sensitiv-

ity must be set such that it does not

detect tooling underneath it with the

rising table at board load height.
