7.3. Warning indications

Warning indications: Indicated by flashing LED display.
Warning Code

The target memory to copy data or to initialize is write protected. Copying any data to

the memory or initializing the memory cannot be executed. Press the [ESC] key to
cancel.
The type of device is different (different in series or voltage class or capacity of inverter).
Press the [ENT] key to copy between two inverters of different capacity or voltage class.
Press the [ESC] key to cancel copying. If "sup" (system area parameters) protection
has been disabled by setting "prot"(memory protection) to "off", the copying

cannot be executed even if the [ENT] key is pressed. Copying to the inverter of a
different series is impossible.
After copying between two inverters with different capacities, the type information
parameters depending on the inverter capacity or voltage class should be initialized. See
the inverter instruction manual on how to initialize them.
Indicated memory is not found or has been corrupted.

or a CRC code error occurred in the selected memory. Press the [ESC] key to cancel.
In this case the data has to be rewritten.
Indicates the title number of the parameter that was found to be different while using
comparison function, or that cannot be written while using the copying function. Press
the [ENT] key to continue, the [ESC] key to cancel.
When Remote Keypad did not find any data in one memory, it flashes "%" in case the
data is missing in the memory that was selected first, or "Hz" if it is missing in the
memory that was selected second. This may happen parameter data may be missing
when the software versions of two inverters are different.

Please press the [ENT] key to continue the comparison.
In this case, CRC code will alternately flash when the comparison is completed.
This situation can be prevented by making the same condition (the state of input or output
terminals, and communication options) of the inverter while copying to the inverter.
However, the unique parameters like IP address cannot be set to same value.
