Control
There are two typical 8520 digital servo drive configurations for the
control. The typical mill configuration has 3-axes, each having a servo
motor and feed back device, and a analog open loop spindle motor. The
typical lathe configuration has 2-axes, each having a servo motor and
feedback device, and a analog open loop spindle motor with position
feedback.
The 8520 digital Servo module functions as a high--speed servo processor.
It is installed in the component enclosure.
