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).
