The Allen-Bradley 1391-DES45-DI-AQB is a sophisticated digital servo drive that excels in controlling the speed and torque of AC servomotors. With its microprocessor-based architecture and compact design, it primarily complements the 1326 Servo motor. This servo drive features an adjustable encoder output offering resolutions of 2048, 1024, 512, and 256 pulses per motor revolution to ensure high feedback accuracy. The front panel is equipped with a Human Interface Module (HIM) that includes a 2-line, 16-character LCD and a user-friendly 5-button keypad for seamless parameter configuration. Operating on a 230V AC (3-phase) input with 50-60 Hz frequency, it boasts a continuous power output of 15 kW, peaking at 30 kW, and supports a broad ambient temperature range of 32 to 104 °F. The system is safeguarded by an integrated 3-pole magnetic circuit breaker and requires a meticulously ventilated enclosure to maintain optimal performance, preventing contamination and ensuring long-term durability. Its dimensions are 482.6 x 157.5 x 293.6 mm, with a weight of 15.4 kg.
