Tip!

You can connect incremental encoders with HTL level that supply signals A and B only, to PIN 2 and

PIN 9. The inputs at PIN 3 and PIN 1 must then be connected to the supply voltage of the incremental

encoder.

The connection is as shown in the figures:

 Use twisted pair cables and screened pair cables.

 Connect the screen at both ends.

 Do not change the cable cross−sections indicated.

7.3.1.3 Touch probe (TP)

Process: The current angle value (encoder input value) is saved by a quick interrupt in the operating

system when a signal changes at the TP activating input (e.g. X3/I1).
