SERCOS (SERiaI COmmunication System) is a communication standard which
defines the digital link (medium and exchange protocol) between the motion control
module and servo drives. This standard is defined in European standard
IEC/EN 61491.
Using the SERCOS distributed architecture enables the application I/O (position
encoder, emergency stop, etc.) to be connected directly to the servo drives, thus
reducing connection costs. The fibre optic digital link permits high speed exchanges
(2
or 4 Mbps) while ensuring total immunity in industrial environments subject to
interference.
The SERCOS range for the Premium automation platform consists of:

(2)
axis control modules that can control up to 8 servo drives
(
TSX CSY 84/85) and 16 servo drives (TSX CSY 164), via a SERCOS ring bus. The
module calculates the path and the interpolation for several axes (position mode).
The other modes (speed and torque) can be accessed using Schneider Electric
application services.
b
1.5
A to 70 A permanent Lexium servo drives
(1)
(
with the SERCOS option).
The servo drives manage the position, speed and torque loops and ensure power
conversion to control the servo motor. The sensor feedback is sent to the servo drive
(
current position, current speed).
b
BDH and BSH servo motors. These have permanent magnets delivering a high
power-to-weight ratio and excellent dynamic speed response in a compact unit.
The Lexium range
(1)
offers all the necessary options (line chokes, braking resistors,
etc.) as well as all connection components.
