EM.4.2 SERCOS CONNECTION
The IEC 1491 SERCOS interface is an international standard for digital communications
between CNCs and servo drives of CNC machines.
The Sercos communications ring integrates several functions.
It carries the velocity command from the CNC to the drive in digital format with greater
accuracy and immunity against outside disturbances. It carries the feedback signal from the
Drive to the CNC. It communicates the errors and manages the basic control signals of the
Drive (Enables). It allows setting, monitoring and diagnosis of the parameters from the CNC
with simple and standard procedures.
All this drastically reduces the hardware required at the Drive, thus, making it more reliable.
Its open and standard structure provides compatibility between CNCs and servo systems
from different manufacturers on the same machine.
