SERCOS

We support SERCOS II and SERCOS III. This is a real-time capable master/slave communications system. The bus system is characterized by high sampling times and low jitter. The SERCOS II bus is implemented as a ring topology via fibre-optic cable. Fibre-optic technology minimizes electromagnetic disturbance over the bus. Reference input is entered cyclically on the servocontrollers. A torque, position or speed can be specified as a reference value.
In SERCOS III the physical transfer is executed over the Ethernet, and so is compatible with existing systems. The synchronization process has been enhanced over SERCOS II, and it offers extended device profiles. It also offers direct device-to-device cross-communication.
