3.6. Auxiliary Encoder Channel / PSO Output (J201)
The auxiliary encoder interface accepts an RS-422 differential quadrature line driver signal. Invalid or
missing signals will cause a feedback fault when the axis is enabled.
The auxiliary encoder interface can be configured for an encoder input or as a PSO output, not both. The
auxiliary encoder is bidirectional but all three signals (SIN, COS, MRK) must be configured for the same
direction. You cannot use the SIN/COS signals as an encoder input while using the MRK signal as the PSO
output. Since the MP does not have any other way to output the PSO signal, you therefore cannot perform
PSO firing if the auxiliary encoder channel is configured for an encoder input.
This encoder channel can be used as an input for master/slave operation (handwheel) or for dual feedback
systems. The auxiliary encoder interface does not support analog encoders and cannot be used as an input
for the -MXU option.
The auxiliary encoder channel can also be used to echo the standard encoder signals or as the PSO output.
Configuring the PSO hardware will automatically configure this encoder channel as an output (refer to
Section 3.6.1. ) and will remove the 180 ohm terminator resistors.

Specification Value
Encoder Frequency 10 MHz maximum (25 nsec minimum edge separation)
x4 Quadrature Decoding 40 million counts/sec
N O T E : Use the EncoderDivider parameter to configure the bi-directional encoder interface on the aux-
iliary I/O connector. The EncoderDivider parameter converts the auxiliary encoder interface to an output
and defines a divisor for the encoder echo. Refer to the Soloist Help file for more information.
