Armor PowerFlex Variable Frequency Drives
Overview
Description
The Armor™ PowerFlex® unit is a variable frequency drive (VFD) and is suited
for variable frequency applications where more precise motor control is
needed. The Armor PowerFlex drives are available in integrated safety
(Bulletin 35S) and standard (Bulletin 35E) versions.
All Armor PowerFlex drives feature an embedded dual-port EtherNet/IP™
switch, which supports star, linear, and DLR topologies.
The Armor PowerFlex drive provides an IP54/66, UL Type 4/12, and NEMA 4/12
enclosure design, which is suitable for water wash down environments, when
appropriate cables are attached or sealing caps are in place.
Fault diagnostic capabilities, including status indicators, are built in to the
Armor PowerFlex drive to help you pinpoint a problem for easy
troubleshooting and quick restarting.
Input and Outputs
All Armor PowerFlex drives include four standard inputs and two standard
configurable I/Os.
The Armor PowerFlex safety drive includes: two test outputs, four safety
inputs, and one bipolar safety output.
IMPORTANT
The Armor PowerFlex drive ships with a rubber sealing boot
which is required to be installed when the power OUT connection
is not in use. (This scenario could apply when daisy chaining is
not in use or when the drive is the last unit in the daisy chain).
When installed, this rubber sealing boot provides an IP54 rating
to the power OUT connection. If a greater IP rating is required, for
example IP66, appropriately rated sealing caps are required to be
installed. For selection information, see Accessories in the
