[Feedback Select]
Selects the source for motor speed
feedback. Note that all selections are
available when 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 & interface check.
