The overview of the SERCOS® architecture is as follows:
Introduction to the Premium Package
The Premium package consists of:
-
the Premium/Atrium PLC range
-
the axis control module TSX CSY 84 which can control up to 8 servodrives via the bus ring,
-
the axis control module TSX CSY 164 which can control up to 16 servodrives via the bus ring,
-
the range of Lexium 17S servodrives (4 A to 56 A): LXM 17S,
-
the range of motors: BPH...,
-
Control Expert is used to configure the TSX CSY 84/164 module and program the motion project.
-
UniLink software which can be used to enter parameters and adjust servodrives.
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/Atrium range. In this case, it will be configured by its own configuration software and not by UniLink.
Functions Performed by the Various Modules
The axis control module TSX CSY 84/164 performs the trajectory calculation and interpolates several 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 servodrives are made via the SERCOS® ring bus.
