The circular digital SERCOS real-time bus realizes the safe data

exchange with the servo drive MC-4. Due to the use of optical fiber

technology, the data bus is insensitive to electromagnetic

disturbances and cyclically supplies the decentralized servo drive

MC-4 with new set values at a data rate of 4MBaud. All internal

states of the axes can be checked via the real-time bus and

processed in the PacDrive Controller.

In addition to digital and analog inputs and outputs, the PacDrive

Controller has two serial interfaces and one Ethernet interface. A

variety of process visualization and control systems can be

connected to the PacDrive™ system via the integrated OPC

interface. Further peripheral components can be connected via field

bus interface modules. The PacDrive Controller can act as a field

bus master or slave.

The international field bus standards CANopen, PROFIBUS-DP

and DeviceNet are supported. The built-in interfaces enable remote

diagnosis via telephone modem or Internet. Via TCP/IP, PC’s can

communicate with the PacDrive Controller and diagnose the state

of the control directly.
