Figure 4.1 SERCOS III communication module for MSD Servo Drive
The power supply to the communication module is provided by the MSD Servo Drive.
Real-time capability permits highly dynamic drive engineering applications with NC cycle
times of 125µs to 65 ms (multiples of 125µs). The data to be transferred is defined in
the SERCOS driver in numerous preference telegrams and parameters. They are specially
tailored to the high demands of electric drive systems. A freely configurable telegram
permits optimum utilization of all the possibilities offered by the line based on additional
setpoint and actual value parameters such as increasing the transferred position resolu-
tion, use of the inputs and outputs in the drive in the NC cycle, and much more.
