The digital inputs are of the NPN type and must be connected to 0V to activate them Encoder inputs

The inputs of the encoder phases are of the NPN type and must be connected to 0V to activate them Analog inputs

Analog inputs accept a voltage range from 0 to 3.3Vdc.

  • For resource mapping (digital inputs, analogue inputs and MPG) refer to the documentation of the board used.
  • If MPGs are not used, Phase A and B signals can be used as digital inputs.
  • In the digital inputs DO NOT connect devices that require NC logic but only NO.

The accessory can be used with control software version 1.9.4 or later.
To enable use in the board settings, set the parameter marked in red as shown in the figure:

For resource mapping (digital inputs, analogue inputs and MPG) refer to the documentation of the board used.
