counter to detect both movement direction
and distance travelled. Devices D+0and D+1
are used to input the phase pulses, while
device D+2is used to input the ‘zero position’
on the rotary table. These devices should be
programmed as shown in the example below
(where the physical termination takes place
at the associated X inputs).
The movement direction is found by checking
the relationship of the two phases of the 2
phase counter, e.g.
