Maintenance
75
Reforming the capacitors
The capacitors must be reformed if the drive has been stored for a year or more. See
page
for information on finding out the manufacturing date. For information on
reforming the capacitors, contact your local ABB representative.
Other maintenance actions
Transfering the memory unit to a new drive module
When a drive module is replaced, the parameter settings can be retained by
transferring the memory unit from the defective drive module to the new module.
WARNING!
Do not remove or insert a memory unit when the drive module is
powered.
After power-up, the drive will scan the memory unit. If a different application program
or different parameter settings are detected, they are copied to the drive. This takes
about 10 to 30 seconds; the drive will not respond while copying is in progress.
