Max. connectable cross-section: 0.5 mm
Type: Spring-loaded terminal 1 (see Appendix A)
1) DI: digital input; DI/DO: digital input/output; M: electronic ground; M2: ground reference
Note
An open input is interpreted as "low".
The "fast inputs" can be used for position sensing.
To enable digital inputs (DI) 4 to 7 to function, terminal M2 must be connected. This can be
done as follows:
Connect the reference mass of the digital inputs, or a jumper to terminal M
(Notice this removes isolation for these digital inputs).
Note
If a momentary interruption in the voltage occurs in the 24 V supply, the digital outputs will
be deactivated until the interruption has been rectified.
