MX350: Incremental Input A, B
The unit provides two inputs at terminal 5 and 7 for HTL signals.
The characteristics of the incremental input (PNP, NPN, Namur or Tri-State) can be set in the GENERAL
MENU.
Wiring of the incremental inputs:
PNP
NPN
Namur
Tri-State
Unconnected PNP inputs are always “LOW” and unconnected NPN inputs are always “HIGH”.
All inputs are designed to receive impulses from electrical impulse sources.
Notice for mechanical switching contacts:
When exceptionally mechanical contacts are used, please connect an external capacitor between GND (-)
and the corresponding input (+). A capacity of 10 µF will reduce the input frequency to
20 Hz and miscounting due to contact bouncing will be eliminated.
