Appendix C Application Notes
Example:
The application is a paper winder. The drive is set for SLAT Min mode, so that
the drive normally runs in torque mode and follows Par 39 [Torque Ref ].
[Torque Ref ] comes from an external controller and is approximately 60% of
motor torque during the snapshot. The speed reference, also from an external
controller, is set just above the speed feedback so the speed regulator is saturated
while in torque mode. The following snapshot captures what occurs in the drive
during a break in the web.
