Communications
When Communication is selected as a speed
reference source, VFD will provide output
frequency based on reference set by
communications.
PID
VFD speed reference will be provided by PID
control based on difference between PID Set‐
pointandFeedbackvalues.WhensettoPID,all
PID parameters will be available. Wh
