3.2. Auxiliary Encoder Channel [-EB1]
You would typically use this interface to read the second encoder in a dual feedback system. The auxiliary
encoder interface accepts RS-422 line driver signals.
It can also be configured as an output to echo internal encoder signals for use by third party hardware. The
EncoderDivider parameter configures the sine and cosine signals as RS-422 outputs. Refer to the Help file
for more information.
When configured as inputs, invalid or missing signals will cause a feedback fault when the axis is enabled.
NOTE: Aerotech recommends that you use twisted pair wiring for all differential signals.
