3.3.6. Customer interface unit (CIU)
The optional customer interface unit (CIU) provides I/O modules to monitor the
transformer and motors (Fig. 3-23). The following units are available:
– CIU provides predefined I/O modules for controlling and monitoring the
auxiliaries of motors and the transformers.
The I/O module modules are connected to the drive controller.
– CIUe provides engineered project-specific interfaces and an application
controller with customer-specific software.
As an option for single-motor drives, it is possible to integrate the predefined I/O
modules (maximum 4 modules in the rooftop extension box (REB) of the water
cooling unit). For more I/O modules, a CIU is required.
