The Allen-Bradley 1771-QC PLC 5 Servo Positioning Assembly is a sophisticated, modular system that excels in industrial motion control applications. Comprising the 1771-M3 servo controller and 1771-ES servo expander module, it allows for scalable axis control, accommodating up to three axes per chassis through additional expander modules. The assembly offers an isolated servo output of ±10V DC with a 12-bit signed digital-to-analog converter, ensuring precise control. Featuring encoder inputs with different frequency modes, a tachometer input with a 50V DC maximum voltage, and selectable discrete input resistance, it delivers versatile operational capabilities. Furthermore, the system supports up to a 9999 ipm/s acceleration/deceleration range, operates efficiently within a temperature range of 0-60°C, and efficiently uses system resources with designated current draws, highlighting its adaptability and robust engineering for demanding environments.
