The 8520-PS1A falls into the category of digital servo cards by Allen Bradley. This high-tech digital servo card by Allen Bradley integrates the tasks of controlling, metering and protecting the functions of the given servo stabilizer of a single unit. The typical setup configuration of the 8520-PS1A digital servo cards comes with 3 axes; each of the axes comes with a specialized servo motor and a proper feedback device. There is also the presence of an open-loop analog spindle motor. The 8520-PS1A digital servo card functions as a high-speed digital servo processor. It is usually installed in the component enclosure of the machine. The 8520-PS1A digital servo amplifier is used to translate the low-level PWM signals from the input of the 8520-PS1A digital servo module to the specific power levels, as required for the driving of the motors. The current feedback for the machine is read from the current sensors of the 8520-PS1A device and its amplifier. The same information (feedback) is returned to the 8520-PS1A digital servo module. Then the received data to the 8520-PS1A digital servo module is processed by the servo module of the device towards maintaining a position of control and velocity, as per the AMP, module, and part program specifications.
It is important to note that when using the solid trapping features that are available on the 9/290 and 9/260 CNC, the Allen Bradley 8510 AC spindle drive system must be used. Once the basic information such as position and velocity are obtained from the given feedback part of the 8520-PS1A device (usually mounted on top of the servo motor), the feedback device is used for generating differential signals. These signals are then fed to the 8520-PS1A digital servo module. If the given spindle motor makes use of an encoder, it will then give the feedback of the spindle position to the specialized 8520-PS1A digital servo module.
