The Allen-Bradley 1388B-AV40 Servo Controller from the 1388B Bulletin is a highly efficient DC servo controller tailored for use with the 1388 Anti-Backlash system. Highlighting its robust performance, this open-frame Series B controller delivers a nominal output voltage of 150VDC, a continuous current of 40 Amperes, and a peak output of 100 Amperes, with a power capacity reaching 3 kW. Designed to enhance servo motor operation, it includes advanced protective features such as electronic motor thermal overload detection and power bus over/under voltage protection, supported by an internal dynamic braking resistor capable of handling 100 Watts. Operating on a 120 VAC, 3-phase power supply, this controller ensures reliable performance through intuitive setup and on-site adaptability, characterized by a straightforward parameter adjustment and a peak current limit adjustment ranging from 10% to 250% of rated current. With a drive efficiency of 85%, the controller maintains optimal functionality within industrial environments, accommodating ambient temperatures between 0 to 60 degrees Celsius.
