What is one way to tell if a drive is still under warranty?
Altivar variable frequency drives
The date of purchase indicated on the distributors invoice or receipt can be used to determine if the drive is in warranty. The standard warranty is 18 months (see FAQ FA117023) . If no receipt or invoice is available the date code of the drive can be used to determine if the drive is in warranty. This date code is imbedded into the number that is located on the right side label of the drive below the bar code. The first 2 digits indicate the manufacturing plant. The next two digits indicate the last two numbers of the year it was manufactured and the next two digits indicate the week of that year. The following numbers indicate the sequence of drive.
example: 8B 092124041 (8B = manufacturing location, 09 = year 2009, 21 = week). The warranty ends November of 2010 (18 months from May 2009).
