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 on page 310 for more information on compatible
resolvers.
ATTENTION: The drive can overspeed if DIP switch S4 is set incorrectly, or the
tachometer is wired incorrectly. Failure to observe this precaution could result in
damage to, or destruction of, the equipment.
