Rockwell Automation 7000L PowerFlex 7000 Medium Voltage AC Drive C Frame - Marine - Manual (Page 337)

Catalog Number Explanation – Drive Selection A-3
7000 “C” Frame - Marine 7000L-UM302B-EN-P – June 2013
The PowerFlex 7000 medium voltage AC drive selection tables are
based on two types of drive service 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.
• Heavy Duty (150% for one (1) Minute, once every 10 minutes)
– used for Constant Torque (CT) or Variable Torque (VT)
applications.
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 five different codes that define service duty and altitude in
the drive catalog number per Table A-2.
For example:
Catalog number 7000 – A105DEHD-R18TX, has a continuous current
rating of 105 amps, with a “normal duty” service rating up to 1000
meters altitude.
Catalog number 7000 – B105DEHD-R18TX 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.
Catalog number 7000 – C105DEHD-R18TX, has a continuous current
rating of 105 amps, with a “heavy duty” service rating up to 1000
meters altitude.
Note: The factory should be contacted for assistance sizing air-cooled
drives that require greater than 150% overload. Refer to Table A-5 for
typical application load torque profiles, to determine which drive
overload rating is best suited for your application.
