Input U

Input this signal when you want to control the mechanical position using the encoder signal. Input a 90 phase difference signal (1x, 2x, 4x) or  input positive (+) pulses on EA and negative (-) pulses on EB. (Two-pulse input)
When inputting 90 phase difference signals, if the EA signal phase is ahead of the EB signal, the motion core will count up (count forward) pulses.
The counting direction can be changed using software.
