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).
For the Compax3 F12, the feedback cable would need to be changed to the F-2C1. A custom motor file will need to be created using the Compax3 Motor Manager software. Here's a link to the videos that step you through this. On the last screen of the Motor Manager, change the standard motor file under Commutation: Digital hall sensor to Automatic commutation with movement.
Note the video shows Commutation angle for a resolver motor but for an encoder it'd be a pull-down selection:
This is shown in the 3rd video of that series at this point in the video:
Note: The newer Pseries cannot be used with hall-less commutation with the Smart Encoder feedback without modifying the F-4A1 cable:
Motors can be converted to standard incremental encoder via a repair RMA. Contact your ATC distributor for price quote.
