electrically out of phase signals, A and B as well as their inverted
signals are generally evaluated. The zero track is needed for the reference point
approach in the positioning module (F5-M/S). Zero track (also reference marking
channel) gives out 1 signal per revolution.
Cable length
To achieve an unobjectionable function following cable lengths should not be exceeded.
Precondition for it is that the supply voltage at the rotary encoder is within the specified
tolerances.
The encoder lines should not be longer than 50 m. If longer cables are needed,
please contact KEB.
Further information can be taken from the documentation of the respective
manufacturer.
