Notes
11 DI/DO 15 B Digital input/digital output 15 (can be used as a high-
speed input of a measuring input or output of an output
cam/DO)
12 G GND Ground
1)
DI: digital input; DI/DO: bidirectional digital input/output; G or GND: electronics ground;
G2: Ground reference
2)
B = Bidirectional; I = Input; GND = Reference potential (ground)
Note
An open input is interpreted as "low".
Connecting terminal G1 or G2 ensures the function of the digital inputs. The following
alternatives are available:
• Connect the carried digital input reference ground to G1 or G2.
• Insert a bridge between terminals G and G1 (or between G and G2).
This removes the electrical isolation for these digital inputs.
3.4.2 Using the digital inputs/outputs
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/outputs are used:
● Digital inputs
● Bidirectional digital inputs/outputs
Bidirectional digital inputs and outputs can be configured individually as digital inputs or
outputs.
Assignment of the inputs/outputs to functions can be parameterized as required. Special
functions (e.g. measuring input input and 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, for example, be switched using the digital inputs.
Digital inputs
The Control Unit has 8 digital inputs.
The electrically isolated inputs can be used as freely addressable inputs.
