PowerFlex 525 Synchronous Reluctance Motor
Configuration
This chapter contains instructions and diagrams on configuring the
PowerFlex 525 drive for use with a Synchronous Reluctance Motor (SynRM)
control.
PowerFlex 525 drive is enhanced with SynRM control that allows an option to
pair with PF525 SynRM for energy efficiency and low effort in motor
maintenance.
SynRM Structure Control Diagram
With PowerFlex 525 drive firmware revision 7.001, SynRM control can only be
configured manually using the keypad.
