Continuation Incremental encoder input (X2)“:
HTL NPN (NAMUR)
TTL (PNP)
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.
