Speed Ref A Sel
Speed Ref B Sel
Selects the speed reference source for the drive. The selected speed reference values converge in the final
selection of the drives speed reference with Par
152 [Applied LogicCmd] and are selected with bits 28, 29, 30.
See the Block Diagrams beginning on page 171

34 S Curve Time
Sets the S time (Round In and Round Out ) in seconds. Half of the time specified is added to the beginning and
half to the end of the applied ramp. The S time is independent of speed and results in a trapezoidal torque profile.
