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 in order to saturate the speed
regulator while in torque mode. The following snapshot captures what occurs in
the drive during a break in the web.
