Memory Unit; Transferring The Memory Unit - ABB ACS880-207 Hardware Manual

Memory unit

When a drive is replaced, the parameter settings can be retained by transferring the
memory unit from the defective drive to the new drive. The memory unit is located on the
control board.
After power-up, the drive will scan the memory unit. If different parameter settings are
detected, they are copied to the drive. This may take several minutes.

Transferring the memory unit


WARNING! Do not remove or insert the memory unit when the drive or control
board is powered from an external power source.
1. Stop the drive and disconnect it from the power line. Wait for five minutes to let the
drive DC capacitors discharge. Ensure by measuring with a multimeter (impedance at
least 1 Mohm) that there is no voltage present.
2. Undo the memory unit mounting screw and take the memory unit up. Replace the unit
in reverse order. Note: There is a spare screw next to the memory unit slot.
