Version 1.0
6.3.1 IO-Link connector M12
Power supply and communication are realized via a 5-pin, A-coded M12
connector.
The unit has a connection according to IO-Link port class B, i.e. two separate,
galvanically isolated supply units. One supply unit is used for the logic, the other
for the motor.
Pin Function
1 +24V DC logic
2 +24V DC motor
3 GND Logic
4 IO-Link communication
5 GND Motor
6.3.2 Functional earth
The functional earth of the unit is connected as standard via an M3 screw on
the housing.
Use a toothed lock washer or contact washer to screw on the connection in
order to break through the anodised layer. This ensures the electrical
conductivity of the connection.
Alternatively, at the customer's request, a shielded IO-Link cable can be used
instead of the standard unshielded cable to connect the functional earth.
WARNING
Danger due to uncontrolled movements!
Due to the IO-Link interface, the control unit can specify commands (possibly
incorrect) due to external influences that do not correspond to the intended
application.

Ensure that the influencing adjacent processes responsible for the
movement of the flange function faultlessly.

If this cannot be ensured, further protective measures shall be taken for this
purpose.
