I have a SICK DFS20A-A2PBD065536 incremental encoder and I am powering it with 24V DC. When I rotate the shaft, I do not get any change in either A or B output signals (Its a quadrature encoder). We are certain the drawings are correct. My question is how protected are SICK encoders (or a industrial rotary encoder in general) to errors in wiring. We know we didn't apply 120V, and no welding has been done.
Encoder set for:
60 PPR (pulse per revoloution)
HTL output (?Totem Pole? / output level based on input power (24V).
It worked when it left thet shop
We tried wiring it in the field, but it didn't work. (possible that we had error in wiring)
We brought back to bench to test, and it no longer works.
- How sensitive are these encoders to miss wiring (shorting a pair of pins together, leaving a common open, 24V applied to the wrong pin. (In your experience?)
