ABB ZMU-02 Replacement Memory Unit Kit

The ABB ZMU-02 Replacement Memory Unit Kit is the removable memory unit for ABB drive control units — compatible with the ZCU-12, ZCU-14, BCU-02, BCU-12 and BCU-22 control units. It stores drive parameters, firmware and application programs, and is required for the drive’s application-programming function (IEC 61131-3) with its associated software license.

- Delivered empty — software is loaded separately (“Software not included” per ABB)
- Licensing enforced: a program loaded without a license key triggers fault 64A5 “Licensing fault”
- Not recommended for ACS880 spare-part use — use ZMU-03 (3AXD50000223107) for ACS880
