Chapter 2 Component Test Procedures
Create a Fault Report Complete fault reports are critical for analysis and repair of modules returned to
the factory.
At a minimum, perform and record the following:
• Record the contents of the fault queue (faults and times of occurrence).
See the PowerFlex Digital DC Drive User Manual, publication
20P-
UM001 , for detailed Fault and Alarm codes and descriptions.
• Make a record of any burn marks on the printed circuit boards, cabling,
bus bars, and SCR modules
• Make a record of any liquid and condensation marks on the printed circuit
boards, components and mechanical parts
• Make a record of the amount of dust and other additional particles on the
drive and drive components
• Make a record of any mechanical damage to the drive and drive
components
• Record the size and type of main fuses
• Record any other important marks and damage
What You Need When You
Call Tech Support When you contact Technical Support, please be prepared to provide the
following information:
• Order number
• Product catalog number and drives series number (if applicable)
• Product serial number
• Firmware revision level
• Most recent fault code
• Your application
You can use the table below to record the data provided in each PowerFlex DC
drive parameter listed.
Param(s) Name Description Parameter Data
1349 Status1 at Fault Captures and displays Par 381 [Drive Status 1] bit pattern at the time
of the last fault.
1350 Status2 at Fault Captures and displays Par 382 [Drive Status 2] bit pattern at the time
of the last fault.
1351-1360 Fault x Code A code that represents the fault that tripped the drive. The codes will
appear in these parameters in the order they occur (i.e., [Fault 1
Code] = the most recent fault).
1361-1370 Fault x Time The time between initial drive power up and the occurrence of the
associated trip fault.
1371 Fault Arm Amps Captures and displays the armature current (as a percentage of rated
current) at the time of the last fault.
1372 Fault Speed Captures and displays the output speed (rpm) of the drive at the time
of the last fault.
1373 Fault Field Amps Captures and displays the field current (as a percentage of rated
current) at the time of the last fault.
1374 Fault Voltage Captures and displays the armature voltage at the time of the last
fault.
