Digital inputs
Definition
The motor starter has 2 digital inputs, which you can connect directly to sen-
sors (PNP) using 2-wire and 3-wire technology.
M12, 5-pole plug connectors are used for this.
M12, 5-pole jacks are fitted on the motor starter.
Pin assignment
The pin assignment is arranged in accordance with the standardized Y2
assignment and the examples for 2- and 3-wire circuits:
Fig. 2-8: Pin assignment with circuit examples
Attention
The digital inputs are short-circuit-proof. The current is limited to a
maximum of 200 mA. In the event of a short-circuit or overloading of the
sensor supply, the switching element (motor) and brake output are deactiva-
ted and a general fault is issued. You must acknowledge this fault with trip
reset.
Attention
Do not use an external power supply because otherwise there will be a risk
of short-circuits.
