Rockwell Automation 7000A PowerFlex Medium Voltage Drive (A-Frame) - Classic Control - Manual (Page 237)

Commissioning 4-63
7000 “A” Frame 7000A-UM150F-EN-P – June 2013
Application of Medium Voltage
Before running the drive on Medium Voltage, it is a good idea to set
up the diagnostic trending feature to capture any information in the
event of a fault during commissioning. REMEMBER TO RESET
THE TRENDING BEFORE LEAVING THE DRIVE IN
PRODUCTION.
The diagnostic trending operation of the drive allows you to capture
the relationships of 8 parameters over a period of time. Trending is a
valuable tool for trouble shooting the drive.
The length of the trend buffer can be set to 100 or 1000 samples.
From the main menu, press the Diagnostics Key (Diags [F9]). This
key enters the user into the Diagnostics Menu. The Options within
the Diagnostics Menu are listed as follows:
 RE-ARM
 D_SETUP
 VIEW
Re-Arm
The re-arm function clears the memory buffer, which contains the
data stored from the previous trend. It is necessary to reset the
trending feature in order for a second trigger to occur, unless you
have continuous trigger enabled.
Diagnostic Setup
The diagnostic setup is used to define the source of the diagnostic
trigger. Information that has to be programmed in the diagnostic
setup is listed below:
Rate The time delay between sample periods. Any value
between 0 and 20,000 msec can be set.
Use numeric keypad to enter the value and press the
enter key to accept.
Post The percentage of the list which will occur after the
trigger point. Any value between 0 and 100% may be
used.
Trace The Read-Only Parameter which is assigned to a
particular list. The item linked to Trace 1 is used as
the trigger value. There are 8 possible traces,
although not all have to be active.
