Operation principle and hardware description

Contents of this chapter

This chapter gives information about the hardware of the control units.

Hardware description

The control unit is an interface for external converter control signals, and it controls converter modules via fiber optic links. The control unit contains a control board and connector boards. The control unit contains integrated branching unit functionality for collecting and storing real-time data from the converter modules to help fault tracing and analysis. The data is stored on a memory card which can be analyzed by ABBservice personnel.

The control unit requires an external 24 V DC power source. It has three option slots for I/O extensions, encoders and fieldbus adapters and functional safety modules, and aremovable memoryunit. If it is necessary to replace the control unit, you can keep the parameter settings by moving the memory unit from the defective control unit tothenewone.ThecontrolunithasoneoptionslotforconnectingaRDCODDCS communication option module. The control unit also has a connection for a control panel.

Thedrive-to-drive link (XD2D) is a daisy-chained RS-485 transmission line that allows basic master/follower communication with one master and multiple followers. The X485 connection provides a connection for the optional CIO-01 I/O module.

The control unit has two Ethernet ports for control network and two Ethernet ports fortool/gatewaynetwork.Environmentalsensorsonthecontrolunitmeasurehumidity and temperature.
