Note
An open input is interpreted as "low".
The "rapid inputs" can be used for positioning measurement.
To enable digital inputs (DI) 0 to 3 to function, terminal M1 must be connected. This can be
done as follows:
Connect the coupled-motion reference ground of the digital inputs, or provide a jumper to
terminal M. (Notice! This removes galvanic isolation for these digital inputs.)

Max. connectable cross-section: 2.5 mm
Type: Screw terminal 2
Note
The two "+" and "M" terminals are jumpered in the connector and not in the device. This
ensures that the supply voltage is looped through.
The current consumption increases by the current consumption of DRIVE-CLiQ and the
digital outputs.
