5.2 Control signals by way of terminals on the Control Unit and Motor /
Power Module
Features
● Only for the Basic Functions
● Two-channel structure via two digital inputs (e.g. Control Unit / power unit)
● A debounce function can be applied to the terminals of the Control Unit and the Motor
Module to prevent incorrect trips due to signal disturbances or test signals. The filter
times are set using parameter p9651.
● Different terminal blocks depending on the format
● Automatic ANDing of up to eight digital inputs (p9620[0...7]) on the Control Unit for
chassis format power units connected in parallel
● The F-DI 0 is available on the CU310-2
