Product Overview

• Part No: ZMU-02, order code 3AXD50000006010
• Brand: ABB

• Category: Frequency Converter Memory UnitZMU-02 is a dedicated pluggable non-volatile memory unit designed for ABB ACS880 series drives. It stores drive firmware, complete user parameter settings, fault logs and motor configuration data. The memory card supports quick parameter backup, restoration and batch duplication, greatly shortening commissioning time for multiple identical inverters. When the control board is replaced, data can be directly loaded to resume normal equipment operation, minimizing production downtime.
