Catalog Number Explanation – Drive Selection A-3

7000 “A” Frame

7000A-UM150F-EN-P – June 2013


The PowerFlex 7000 “A” Frame medium voltage AC drive selection
tables are based on two (2) types of drive service duty ratings:


1) 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.

2) Heavy Duty (150% overload for one (1) Minute, once every 10

minutes) – used for Constant Torque (CT) applications only.

Drives with this rating are designed for 100% continuous operation
with 150% 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 7000A – A105DED-R6TXI, has a continuous current
rating of 105 amps, with a “normal duty” service rating up to 1000
meters altitude.


Catalog number 7000A – B105DED-R6TXI has a continuous rating of
105 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.
