A.6 Feedbacks
A.6.1 Feedback Supply Voltage
The Drum has two feedback ports (main and auxiliary). The drives supply voltage to the
main and auxiliary feedback devices (200 mA to the main feedback and 200 mA to the
auxiliary feedback).
Feature Details
Main encoder supply voltage 5 V +5% @ 200 mA
Auxiliary encoder supply voltage 5 V +5% @ 200 mA
