Rockwell Automation 7000L PowerFlex Medium Voltage AC Drive (C Frame) - Classic Control - Manual (Page 539)

Catalog Number Explanation – Drive Selection A-3
7000 “C” Frame 7000L-UM300I-EN-P – June 2013
The PowerFlex 7000L medium voltage AC drive selection tables
are based on normal duty service ratings: (Contact factory for
heavy duty ratings)
 Normal Duty (110% overload for one (1) Minute, once
every 10 minutes) – used for Variable Torque (VT)
applications only.
Drives with this rating are designed for 100% continuous operation,
with 110% overload for one (1) minute, once every 10 minutes.
Service Duty Rating, Continuous Current Rating, & Altitude
Rating Code
There are different codes that define service duty and altitude in the
drive catalog number per Table A-2.
For example,
Catalog number 7000L – A575DEHD-R18TX, has a continuous
current rating of 575 amps, with a “normal duty” service rating up
to 1000 meters altitude.
Catalog number 7000L – B575DEHD-R18TX has a continuous
rating of 575 amps with a “normal duty” service rating up to 5000
meters altitude. Please note that the ambient temperature rating of
the drive is reduced at higher altitudes. If 40°C ambient is required
at 1001-5000 meters altitude, then a rating code of Z is required.
Note: The factory should be contacted for assistance sizing
liquid-cooled drives that require greater than 110% overload,
or are being applied to constant torque loads. Refer to Table
A-5 for typical application load torque profiles, to determine
which drive overload rating is best suited for your application.
