8520-AA6

The 8520-AA6 module is a servo amplifier manufactured by Allen-Bradley; it is a part of the 9 series CNC of amplifiers. Servo amplifiers are one of the main parts that servo motors utilize to improve general functioning. Servo motors are used to drive the axes of a machine; the task of the servo amplifier is to improve the amount of power delivered to the servo motor. It is also there to guarantee that the servomotor is receiving all the power it needs for an optimum functioning. The main function of the Allen-Bradley 8520-AA6 servo amplifier is to receive and amplify the signal from a 9/230 processor so that it can then deliver the necessary energy to power the servo motors. The Allen-Bradley 8520-AA6 servo amplifier operates with 6 Amps and possesses two servos. This unit also features a Teflon shaft seal, enabling it to be applied above flood line operations. This servo amplifier can be paired with the digital 9/230 CNC 8520 drive version and with any servo motor, so long as they are actually compatible with each other. When it comes to the installation of the Allen-Bradley 8520-AA6 servo amplifier, it should be separated or isolated from the processor module because of the electrical noise it generates.

The Allen-Bradley 8520-AA6 servo amplifier has two typical configurations for its optimum control. The 8520 digital servo module provides low-level signals PWM to the 850 servo amplifier; this unit them translates those signals to the power levels that the servo motor requires. The Allen-Bradley 8520-AA6 servo amplifier has sensors equipped with the ability to catch feedback in order to make it readable by the digital servo module.
