Connecting sensors and actuators
Digital inputs and outputs can be used to connect various sensors and actuators to the 14-pin
connectors X122 / X132 / X142 on the front panel. The interfaces are permanently assigned:
• X122 and X132: Drive
• X142: Control.
The following types of digital I/O are used:
• Digital inputs (isolated)
• Digital outputs
• Bidirectional digital inputs/outputs (only for drive terminals)
The assignment of I/Os to functions can be parameterized freely by the user. Special functions,
such as probe inputs (rapid inputs only) and cam outputs, can also be assigned to the inputs/
outputs.
The enables for the drive units and/or motors (Line Module, Motor Module) connected to the
NCU can be switched using the digital inputs.
Note
Terminal assignments
When commissioning the drive wizard, the digital inputs/outputs are correspondingly
preassigned functions.
For more information about terminal assignment, see:
• System Manual Guidelines for the Machine Configuration
Access to digital inputs/outputs
Note
The digital inputs/outputs of the drive terminals are updated in accordance with the set
PROFIBUS bus clock cycle of SINAMICS Integrated.
Note
If the DI/DQ interfaces X122, X132 and X142 are operated partially as DI and partially as DQ
(mixed operation), then the DI must be operated with the same power supply as the NCU
module power supply X124. This applies to hardware versions frame size A to E
