The AKD2G's various feedback options allow for incorporating up to 5 feedback devices into the drive. Occasionally the feedback is not used for servo AXIS control (a position used as a direct command or feedback to a servo axis) but used as an additional or axillary feedback signal for the motion/machine controller (PCMM, etc). The controller utilizes the position as a master or reference position. The attached application note covers the setup and scaling of this position that is sent through EtherCAT.
