AXIMA 2000/4000 Installation Manual
Encoder Inputs
Encoder signals are low voltage, high frequency signals susceptible
to noise if not properly shielded. For reliable operation it is important
that encoder cables be shielded and routed away from motor power
or other high voltage signals. Shields should be connected at the
controller end.
Table 6 Encoder Signals
The encoder signals may come from an encoder or from the encoder
simulation output of a brushless servo drive (see wiring diagrams
below).
