Encoder outputs meet RS-422 driver specifications and can drive up to 10 RS-422 signal receivers. Each
differential pulse input is an RS-422 line receivers. The default encoder output resolution is 2048 lines per
motor revolution. This resolution is adjustable in one line per revolution increments with PowerTools Pro
software. The range is between 1 and the actual motor encoder density.
