DI: Digital input; DI/DO: Bidirectional digital input/output; M: Ground M1: Ground reference
Note
An open input is interpreted as "low".
The "rapid inputs" can be used for position detection and as inputs of measuring inputs
depending on the terminal assignment used.
To enable digital inputs (DI) 0 to 3 to function, terminal G1 must be connected. This can be
done as follows:
Connect the coupled-motion ground reference of the digital inputs or provide a jumper to
terminal M. (Notice! This removes the galvanic isolation for these digital inputs.)
