Description
The Control Units
● CU305 PN (PROFINET)
● CU305 DP (PROFIBUS)
● CU305 CAN
are components in which the open-loop and closed-loop control functions for a drive are
implemented.
The table below shows an overview of the interfaces of the CU305 Control Units.

1)
The bidirectional digital inputs/outputs are designed as "rapid inputs" and can be used for BEROs
(3-wire) or measuring probes.
2)
If the safety functions of the Control Unit are not being used, the failsafe digital inputs can be used
as 6 additional electrically isolated digital inputs.
3)
If the safety functions of the Control Unit are not being used, the failsafe digital input can be used
as 1 additional electrically isolated digital input.
