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
single-ended (unsymmetrical).
• For best performance, we strongly recommend using encoders with a line driver. Otherwise, lim-
itations may apply due to slow switching edges.
• Even though 2-channel will do, we strongly recommend to use only 3-channel versions.
