Introduction
This manual explains how to get a Redler Rayon motor drive working with your motor, from choosing a drive to its first controlled motion, and how the drive behaves once it is running. Follow it in order when commissioning a new axis, or jump to any section when you need a specific answer.
Not covered here: the communication protocol, which is in the Serial Communication User Manual (RRUSM000013), and product-specific ratings and pin-outs, which are in each product's datasheet and electrical ICD.
