This port consists of three differential input/output channels (per axis) that take their functions from the Basic
Setup of the drive. With quad A/B motor encoder feedback, the port works as an output, buffering the signals
from the encoder. With resolver or sin/cos encoder versions, the feedback is converted to "emulated" quad
A/B/X signals with programmable resolution. These signals can then be fed back to an external motion
controller that closes the position or velocity loops. As an input, the port can take quad A/B signals to produce
a dual-loop position control system or use the signals as master-encoder commands in camming mode. In
addition, the port can take stepper command signals (CU/CD or Pulse/Direction) in differential format. Absolute
encoders are used frequently for feedback of the load position with the motor using incremental feedback for
commutation and velocity feedback.
