      Hello,

      What is the voltage range that the Stop 11 (ENC_A) and the Stop 10 (ENC_B) pins in the CONN_LCD connector in the Duet 2 Wifi can take?

      Can the take a negative voltage?

      Thank you!
      D

          @Phaedrux I want to get a signal from a drive that tells me whenever the motor connected to the drive faults. The signal may be negative. I don't need to worry about polarity on the drive side. Wondering if the Duet Wifi cares.

            @dieguito those pins connect directly to the microcontroller, so negative voltages are unsafe and may damage it.
