Proximity Switch
Verify that the target
sensor is being seen by the
proximity switch every time
the target is lined up with
the proximity switch using
the Z Edge Count (D1)
Verify that there is no noise
on the proximity switch
channel by verifying that
the Z Edge Count (D1) isn’t
incrementing/decrementin
g more than once per
motor rotation
Check that the proximity
switch power supply on
TB1-17 and TB1-18 is 12V
DC
Verify that SW2 is switched
to the 12V position (at
right). Verify that the
voltage between TB1-17
and TB1-18 is 12 volts DC
