Allen Bradley 1391B-AA45N Used Surplus

The Allen-Bradley product with part number 1391B-AA45N belongs to the 1391 Servo control product family. Servo controllers interface with servo motors to enable motion and position control, mainly used in manufacturing and production processes.

Servo controllers depend on encoder feedback to locate the current position of the mechanism being controlled be it a linear and rotary motion control applications. Production conveyors, pick and place robotic arms, rotary lathe machines are some of the most common installation of a servo controller.

This servo controller features a form factor not higher than 1.03 with peak current limit adjustment of 20 to 200% of Rated motor current. The minimum controller efficiency at rated load is 85% and the controller’s modulation frequency is +/- 2500 Hz.

This servo controller has an open frame. The components inside is covered by a slidable front cover. Appropriate enclosure protection must be installed to protect the drive from environmental interferences and contaminants. Evaluate accordingly if a climate control component may be installed such a fan or a heater. If vented with ambient air, filters must be installed to prevent damage caused by entry of oil, dust, condensation and other contaminants.

The operating altitude of this servo controller is up to 1000 meters without deration. For every 305 meters, the motor performance derates by 3%. The 1391-AA45N has power dissipation of 104 Watts @ 20%, 208 Watts @ 405, 312 Watts @ 60 % 416 Watts @ 80 % and 520 Watts @ 100%. With the provided power dissipation, an appropriate fan may be installed that evacuates air from the panel. The enclosure temperature must be not more than 60 Deg. Celsius.

The Allen-Bradley 1391B-AA45N belong to the TL series of low inertia and high-performance servo motors. This product is designed to offer a significant power with a small footprint. The servo controller’s input requirements are 230-volts, 3-Phase. The motor is available in Four (4) varieties, each capable of continuous stall torque range of 0.096 to 5.42 N-m (0.85 to 48 pounds on an inch) and peak torque range of 0.22 to 13 N-m (1.94 to 115 pounds on an inch). The 1391B-AA45N has a high-resolution response, which enables tighter position control with a 17-bit resolution, higher inertia mismatch capabilities, and the ability to control higher load-to-motor rotor inertia ratios while maintaining a stable system. Additionally, the motor offers an absolute encoder ability, which eliminates the need for developing a homing routine. It comes with a standard single-turn high-resolution response, however, the multi-turn high-resolution response is also available. The 1391B-AA45N applies smart motor technology, including an onboard memory that helps retain motor identity and serial communication. This servo controller comes with 46, 70, 90 and 115-millimeter frame sizes and economical power specifications. It included a 24-volt brake option and IP43 seal standard. Shaft seal kits are available to provide a motor surface-only IP65 rating.
