PowerFlex 7000 Drive
Selection Explanation The PowerFlex 7000 medium voltage AC drive selection tables are based on two
types of drive service duty ratings:
1. Normal Duty (110% overload for one minute, once every ten minutes)
– used for Variable Torque (VT) applications only.
Drives with this rating are designed for 100% continuous operation, with
110% overload for one minute, once every ten minutes.
2. Heavy Duty (150% overload for one minute, once every ten minutes) –
used for Constant Torque (CT) applications only.
Drives with this rating are designed for 100% continuous operation with
150% overload for one minute, once every ten minutes.
Service Duty Rating, Continuous Current Rating and
Altitude Rating Code
There are different codes that define service duty and altitude in the drive catalog
number (see
Catalog Number Explanation on page 169 ).
EXAMPLE Catalog number 7000 – A160DED-RPDTD, has a continuous current rating of
160 A, with a “normal duty” service rating up to 1000 m altitude.
Catalog number 7000 – D185TEDY-RPDTD has a continuous rating of 185 A
with a “heavy duty” service rating up to 5000 m altitude.
The ambient temperature rating of the drive is reduced at higher altitudes. If
40 °C ambient is required at 1001...5000 m altitude, a rating code of Z is
required.
