Feedback Signals in Open Loop
In some drives, feedback signals and feedback parameters are only
used in closed loop operation. In the TR1, the feedback signals are
also active in open loop operation. Although they dont effect the speed
of the drive, they can be displayed on the drives meters. Parameters
227 and 228 can set high and low limits for the feedback signals, which
can activate warnings.
For open or closed loop operation, the feedback signal is scaled in
parameters 413 and 414 Minimum and Maximum Feedback, and the
unit displayed is chosen in parameter 415, Process Units.
