For crossing an Ultra 3000, one of the main things to pay attention to is the communication protocol being utilized.  If the drive is a standalone, take a look at the “No Motion Controller” column.  If there is communication over DeviceNet or Sercos, please make sure your controller will be able to handle Ethernet communication.  Please contact me if you have any questions.

You can currently purchase a 1326AB or 1326AS motor along with many other older Allen Bradley servos now made by Elwood (an Encompass partner) through CED.  If you are looking to modernize your system, see below for options to cross to an MPM or VPC motor.

See below for the different breakout boards along with motor/drive compatibility.
