PowerFlex 7000 Drive
Selection Explanation
7000 "A" Frame
The PowerFlex 7000 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 (see page B-1).
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.
