The Allen-Bradley 1391-AA22 is an AC Servo Controller Module. It has a nominal output bus voltage of 300V DC. The module's continuous current (RMS) is 22.5A, and its peak current is 45A. The continuous power output is 7.5 kW, while the peak power output is 15 kW. The 1391-AA22 has a circuit breaker rating of 26A RMS and 1300A (symmetrical amperes). It weighs 12.6 kg (28 lb.). The module's static gain is 1.5 times the rated motor current, and its form factor is 1.03 or less. The efficiency of this module is approximately 85%. The Allen - Bradley 1391 - AA22 has a modulation frequency of 2500 Hz ± 10%. The motor should rotate in a slow and controlled manner. If the motor becomes uncontrolled, rotates incorrectly, or acts erratically, all power should be removed and the wiring should be checked.

The Allen-Bradley 1391-AA22 also complies with certain Electromagnetic Compatibility (EMC) standards. It has passed the EN 50081-2 EMC Generic Emission Standard and the Generic Immunity Standard for industrial environments. The ambient temperature for this module ranges from 0 - 60 °C (32 - 140 °F), and the storage temperature ranges from 0-65° C (32 - 149° F). The relative humidity of the 1391-AA22 is 5-95% without condensation. This module can be placed at an altitude of 1000 meters (3300 feet) and operate without derating. The integral fan output of this module is 50 CFM (unloaded).
