The PC840 servo drives series from Pacific Scientific (Rockford, IL) uses SERCOS interface for closed-loop, real-time distributed control. The SERCOS chip ensures each drive receives update commands, such as positioning, velocity, or torque, from the controller as fast as every 500 microseconds. This can increase network speeds by 400%. Provides noise immunity, complies with IEC/EN 61491, and integrates with any SERCOS-supporting control or device.
