Data protection
You can protect data saved in the keypad from unexpected modifications. Enabling the data protection that was disabled
changes the display
read
on the "Data Copying" function list to
proT
, and disables to read data from the inverter.
To enable or disable the data protection, follow the next steps.
(1) Select the "Data Copying" (
'cpy
) on the function selection menu in Programming mode.
(2) When the
'cpy
is displayed, holding the key down for at least 5 seconds alternates data protection status between
enabled or disabled.
For switching the data protection status, be sure to hold the
key down for at least 5 seconds
. Once the key is
released within 5 seconds, press the
key to go back to the
'cpy
display and perform the keying operation again.
• Enabling the disabled data protection

While
'cpy
is displayed, holding down the key for at least 5 seconds shows

If data copying does not work
Check whether
err
or
cper
is blinking.
(1) If
err
is blinking (a write error), any of the following problems has arisen:
• No data exists in the keypad memory. (No data read operation has been performed since shipment, or a data read
operation has been aborted.)
• Data stored in the keypad memory contains any error.
• The models of copy source and destination inverters are different.
• A data write operation has been performed while the inverter is running.
• The copy destination inverter is data-protected. (function code F00 = 1)
• In the copy destination inverter, the "Enable write from keypad" command
WE-KP is OFF.
• A data read operation has been performed for the inverter whose data protection was enabled.
(2) If
cper
is blinking, any of the following problems has arisen:
• The function codes stored in the keypad and ones registered in the inverter are not compatible with each other. (Either of
the two may have been revised or upgraded in a non-standard or incompatible manner. Consult your Fuji Electric
representative.)
