PowerFlex DC Drives Resolver Feedback Module
The resolver feedback module (catalog number 20P-RES-A0), which provides a drive interface to a selection of compatible resolvers, must
be ordered and purchased separately from the drive. The resolver option module includes the PowerFlex DC Drive Resolver Feedback Module
Installation Instructions, publication 20P-IN071 , which provides installation and wiring information. See ‘Resolver Type Selection’ in the
PowerFlex Digital DC Drive User Manual, publication 20P-UM001 , for more information on compatible resolvers. The PowerFlex DC drive is not
CE Certified when the resolver feedback module is installed in the drive.
ATTENTION: The drive can overspeed if DIP switch S4 is set incorrectly, or the tachometer is wired incorrectly. Failure to
do so could result in damage to, or destruction of, the equipment.
