The MMI displays the message opposite.
Acknowledge the message by pressing the E key. This
action automatically loads and saves Macro 1 default
parameters and the ENGLISH 50Hz Product Code.

you must reload the Product Code of your choice, reload
the macro of your choice, and perform a Parameter Save (SAVE/COMMAND menu) in that
order.
If data will not save correctly, the Operator Station will display a failure message. In this case,
the Inverter has developed a fault and must be returned to Eurotherm Drives. Refer to Chapter 8:
