[Feedback Select]
Selects the source for motor speed feedback.
Note that all selections are available when you
are using Process PI.
“Open Loop” (0) - no encoder is present, and
slip compensation is not needed.
“Slip Comp” (1) - tight speed control is needed,
and encoder is not present.
“Encoder” (3) - an encoder is present.
“Simulator” (5) - Simulates a motor for testing
drive operation and interface check.
