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 JCU Control Unit, see page 27.
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.
