Smart Encoder Q option Feedback option (or 3E option on MPP/MPJ motors) is only compatible with Aries Series Encoder Amplifiers. This encoder will allow the Aries to know what type of motor it is without having to go through the configuration wizard.
This encoder will work with other drives as a standard encoder; however there is no hall-effect feedback. Note that the encoder feedback is the standard 2000line (8000 ppr post-quad) TTL quadrature output. Since the halls are not used, these motors could be used with any drive capable of hall-less startup (Aries with OHALL4, Compax3 F12 with sensorless startup, Gemini with a custom operating system, etc).
