Transferring 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 may
take a few moments; the LED display will read “L” while copying is in progress.
