The Allen-Bradley 1391-DES45-DI is a single - axis digital AC Servo drive with an integral LCD. The display consists of 2 lines with 16 characters, and input can be made through a 5 - button keypad. Red/green LED status indicators are also provided for easy status monitoring. Usually used in an automated machine servo system, the 1391-DES45-DI drive has built - in protection, including an integrated circuit breaker, an integral shunt regulator on the standard 300V DC power bus supply, a shunt regulator resistor, and a power line/DB contactor.
