Encoder Feedback Direction

The encoder can spin either CW or CCW for a given table direction

and the direction (phasing) of the feedback could be backwards.

You can change the direction of the feedback by switching channel A

wiring with channel B wiring. For encoder feedback connections, see

Figure 5.13 and 5.14.

Location: Shows:

1 Channel A is high for at least part of marker interval. You connect this

to CH A.HI of the termination panel.

2 High marker interval. You connect this to CH Z.HI of the termination

panel.

3 B is high for at least part of marker interval. You connect this to CH

B.HI of termination panel.
