5.2.4 Limit Switch Connection X2
Fig. 6: Pin assignment of the limit switches
Fig. 7: Input wiring
The module is designed for connection of up to three limit switches type PNP-NOC/NCC.
A limit switch is determined for monitoring the movement in the + direction (limit ), the
second in the – direction (limit switch –). The third switch (centre switch) for example can be used
as a reference switch. The switch type PNP NCC has the advantage that cable breaks can be
detected.
Mechanical limit switches (NCC) can also be used.

CAUTION – Possible damage!
Damage of the module by wrong connection.
- Do not exchange the 10 pin connector for limit switches with the
10 pin connector for the encoder evaluation. Module and encoder can be
damaged.
