Allen-Bradley 1391B-AA15-A12 AC Servo Controller

The 1391B-AA15-A12 servo controller is an Allen-Bradley/Rockwell Automation AC Servo 1391 Series B servo controller. This Series B controller can be used in most of the same applications as the Series A controller models. The 1391B-AA15-A12 servo controller can connect to a servo motor and to cables from the Allen-Bradley Bulletin 1326 series to make a complete Allen-Bradley servo system. This servo controller operates with 15 Amps of continuous current.

The controller 1391B-AA15-A12 has an electronic static gain of 1.5 times the motor rated per RPM and a form factor of 1.03 or less. It has a load - dependent adjustable peak current limit from 20% to 300%. Its load - dependent efficiency is 85%. The carrier frequency range is 2500 Hz ±10%. It has a 0.07 rpm per degree Celsius maximum drift and zero dead - band. It also has a 0.05% maximum speed regulation change interval at 95% load.
