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 system
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
control unit 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 the terminal assignment see:
Commissioning Manual "Commissioning CNC: NCK, PLC, drive", Chapter "Communication
interfaces and terminal assignment"
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.
