CHAPTER 4 - Start-up and adjustment of the drive
4.3.2 Encoder emulator output terminal J2
Encoder emulator signal can be supplied both in a unipolar and in a differential way. The
selection between the two ways is carried out by the manufacturer, according to the
configuration ordered.
Technical characteristics of the outputs:
Number of pulses/rev.
Zero notch
Output voltages
Connection of encoder emulator:
To connect encoder emulator, please follow instructions below very carefully. The incorrect
execution of signal connection can cause bad operating or even a failure of the encoder
emulator.
