GUIDE FOR CAPACITOR REFORMING IN ACS50, ACS55,

ACS150, ACS310, ACS350, ACS355, ACS550, ACH550 and

R1-R4 OINT-/SINT-boards.

1 Reforming

The drive DC link capacitors need to be reformed (re-aged) if the drive has been non-

operational for more than one year. Without reforming, capacitors may be damaged

when the drive starts to operate. The reforming methods introduced in this instruction

require that the drive has been stocked clean and dry. It is recommended to reform the

capacitors once a year.

1.1 How to check the drive’s age

Check the date of manufacture for the drive from the serial number shown on the drive

labels. The serial number defines the year and week when the drive was manufactured.

There are two formats of serial numbers. Check which format the drive has and

determine the date of manufacture:

Format 1:

YWWXXXXX (8 digits)

Y = year (...6,7,8,9,A,B... for ...2006, 2007, 2008, 2009, 2010, 2011...)

WW = week

Format 2:

XYYWWXXXXX (10 digits)

YY = year (...06,07,08,09,10... for ...2006, 2007, 2008, 2009, 2010...)

WW = week
