Components of the 2-axis handling module with stepper motor
The electrical interfaces, as well as the valve terminal and the motor controller, are mounted to the back of
the module. The electrical interfaces are implemented in the form of miniature I/O terminals:

The controller's inputs/outputs are connected to the station's PLC and evaluated via the upper mini
I/O terminal (4). The bit codes for the various axis positions are also made available by this mini
I/O terminal. The controller's status can also be queried, e.g. "drive ready" or "drive homed".

Data exchange between the station's PLC and the pneumatic Z-axis is implemented via the lower mini
I/O terminal (13). The valve terminal is actuated in order to control Z-axis motion and to open or close
the gripper. At the same time, Z-axis positions can be queried.
