Note: R1, R2, and R3 must be mounted within 3 ft [1m] of the end drive.

= Twisted Pair

A 120 ohm resistor is recommended for high frequency (over 250 kHz) stepping or cable lengths longer than 25 feet.

Figure 42: Master/Slave Encoder Connections

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.
