3.5 Digital I/Os

SIMOTION D4x5-2

Manual, 02/2012

Pin Designation

Signal type

Notes

12 DI/DO 14 B Digital input/output 14 (can also be used as input for

measuring input or as input for the external zero mark)

13 DI/DO 15 B Digital input/output 15 (can also be used as input for

measuring input or as input for the external zero mark)

14 M GND Ground

DI: Digital input; DI/DO: Bidirectional digital input/output; M: Electronics ground;

M2: Ground reference

B = Bidirectional; I = Input; GND = Reference potential (ground)

Note

An open input is interpreted as "low".

To enable the digital inputs to work, terminal M1 or M2 must be connected. The following

alternatives are available:

• Connect the carried digital input reference ground to M1 or M2.

• Insert a bridge between terminals M and M1 (or between M and M2).

This removes the electrical isolation for these digital inputs.
