Best Practice
The use of encoder with built-in line driver is mandatory.
Even though 2-channel will do, we strongly recommend to use only 3-channel versions!
By default, the controller is set for a 500 count per turn encoder. For other encoders, you will need to
adjust respective settings via software.
