Chapter 5 Commissioning the Drive
Application of Medium Voltage
Before running the drive on Medium Voltage, configure the diagnostic trending
feature to capture information in case of fault during commissioning.
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 is 100 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:
ATTENTION: Remember to reset the trending before leaving the drive in
production.
Rate The time delay between sample periods. Set any value
between 0 and 20,000 msec.
Use numeric keypad to enter the value and press [Enter]
to accept.
Post The percentage of the list which will occur after the
trigger point. Set any value between 0 and 100%.
Trace The Read-Only Parameter assigned to a particular list. The
item linked to Trace 1 is the trigger value. There are 16
possible traces, although not all have to be active.
