MultI-Mode encoder port: coMMand Inputs
AS A MASTER OR CAMMING ENCODER INPuT
FROM A DIGITAl quADRATuRE ENCODER
When operating in position mode the multi-
mode port can accept digital command signals
from external encoders. These can be used to
drive cam tables, or as master-encoder signals
when operating in a master/slave configuration.

DIGITAl quADRATuRE ENCODER FORMAT
The multi-mode port can also be used when
digital command signals are in a differential
format. These are the signals that typically
go to single-ended inputs. But, at higher
frequencies these are likely to be differential
signals in which case the multi-mode port
can be used.
MultI-Mode encoder port: feedback outputs
AS BuFFERED OuTPuTS FROM A DIGITAl
quADRATuRE PRIMARy ENCODER
When using a digital quadrature feedback encoder,
the A/B/X signals drive the multi-mode port output
buffers directly. This is useful in systems that use
external controllers that also need the motor feedback
encoder signals because these now come from J12,
the Control connector. In addition to eliminating "y"
cabling where the motor feedback cable has to split
to connect to both controller and motor, the buffered
outputs reduce loading on the feedback cable that
could occur if the motor encoder had to drive two
differential inputs in parallel, each with it's own
121 ohm terminating resistor.
AS EMUlATED QUAD A/B/X EnCoDER oUTPUTS
FROM AN ANAlOG SIN/COS FEEDBACK ENCODER
Analog sin/cos signals are interpolated in the drive with
programmable resolution. The incremental position
data is then converted back into digital quadrature
format which drives the multi-mode port output
buffers. Some analog encoders also produce a digital
index pulse which is connected directly to the port's
output buffer. The result is digital quadrature A/B/x
signals that can be used as feedback to an external
control system.
