3.3.5 Encoder (X5)

Best practice

• Differential signals offer good resistance against electrical interference. Therefore, we recommend

using a differential scheme. Nevertheless, the controller supports both schemes – differential and sin-

gle-ended (unsymmetrical).

• For best performance, we strongly recommend using encoders with a line driver. Otherwise, limita-

tions may apply due to slow switching edges.

• Even though 2-channel will do, we strongly recommend to use only 3-channel versions.
