5. Base I/O Unit (FCU6-DX2**/3**/4**) Connection
5.1 Base I/O Unit Outline
The base I/O unit is used in the connection of the machine input/output (DI/DO), servo drive unit,
spindle encoder, skip and remote I/O unit. There must be one base I/O unit for each NC Card.
Depending on the base I/O unit type, connection is possible with analog input, analog output and a
manual pulse generator.
The following shows a list of base I/O units and add-on PCBs.
