Replacing the memory unit

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. The memory unit is
located in the control unit, see page 38.
WARNING! Do not remove or insert the memory unit when the drive module is
powered.
After power-up, the drive scans the memory unit. If a different control program or different
parameter settings are detected, they are copied to the drive. This can take several
minutes.
To remove the memory unit:
1. Stop the drive and do the steps in section
18 before you start the work.
2. Remove the fastening screw.
3. Pull the memory unit out.
Insert the memory unit in reverse order.
