Third-Party Permanent Magnet Motors
The PowerFlex 755 drive can support third-party permanent magnet motors
without the need of custom profiles. However, the motor nameplate information
sometimes needs to be modified. Rockwell Automation Technical Support
requires the following information to assist you in modifying the motor data for
use with the drive. Please complete the following tables and email the
