Basic information about the drive system

14.6 Inputs/outputs

● Separate power supply for the digital outputs.

● Source of output signal can be selected by parameter.

● Signal can be inverted by parameter.

● Status of output signal can be displayed

– As a binector output

– As a connector output

Before the digital outputs can function, their own electronics power supply must be connected.

Control Unit 310-2

Bidirectional digital inputs/outputs

Signal processing using the bidirectional inputs/outputs is shown in the function diagrams listed

● Can be parameterized as digital input or output.

● When set as digital input:

– Six "high-speed inputs" on Control Unit

– The properties of the "pure" digital outputs apply.

● When set as digital output:

– The properties of the "pure" digital outputs apply.

● Sharing of bidirectional input/output resources by the CU and higher-level controller (see

Section "Use of bidirectional inputs/outputs on the CU (Page 801)")

Terminal Board 30 (TB30) -

isolated digital inputs (DI 0 ... DI 3)

Terminal Module 31 (TM31) -

Digital relay outputs, electrically isolated (DO 0 ... DO 1)

CU310-2 input/output terminals -

digital output (DO 16)

If these inputs are used, for example, for the "flying measurement" function, they act as

"high-speed inputs" with virtually no time delay when the actual value is saved.
