Use Of X122 And X123 Interfaces - Siemens SIMOTION D45 Series Manual

Interfaces
3.4 Digital inputs/digital outputs
Note
An open input is interpreted as "low".
The "rapid inputs" can be used in conjunction with a measuring system for position sensing.
To enable the digital inputs to work, terminal M1 or M2 must be connected. This can be done
as follows:
• Connect the ground reference of the digital inputs.
• Connect a jumper to terminal M (notice: this removes the galvanic isolation for these

Use of X122 and X123 interfaces

Connecting sensors and actuators
Digital inputs and digital outputs can be used to connect various sensors and actuators to
the two 12-pin X122 and X132 front panel connectors.
The following types of digital inputs/digital outputs are used:
• Digital inputs
• Bidirectional digital inputs/digital outputs
Bidirectional digital inputs and digital outputs can be assigned separately as a digital input or
digital output.
Assignment of the inputs/outputs to functions can be parameterized as required. Special
functions, such as input of the measuring input and output of the output cam, can be
assigned to the inputs/outputs.
The enables for the drive units and/or motors (Active Line Module, Motor Module) connected
to the control unit can be switched using the digital inputs.
Digital inputs
The control unit has 8 digital inputs.
The isolated inputs can be used as freely addressable inputs.
