Overview
The overview of the SERCOS® architecture is as follows:
Introduction to the Premium Package
The Premium package consists of:
Functional Diagram
The following diagram shows the different functions performed by the motion controller and servodrives:
NOTE: It is possible to use a servodrive that is not in the Premium range. In this case, it will be configured by its own configuration software and not by UniLink.
Functions Performed by the Various Modules
TSX CSY 84/85 motion controllers calculate trajectories and interpolate multiple axes.
The servodrive controls the position, speed and torque loops. It also provides the power conversion to control the motor. The encoder information is sent to the servodrive (current position, current speed).
Exchanges between the PLC and the motion controller are made via the bus X at the bottom of the rack.
Exchanges between the motion controller and the servo drives are made via the SERCOS® ring bus.
