to write the password to the Move to Protect Level parameter. When the
correct password is written, the display will change to the Operation/
Adjustment Protect parameter and writing the parameters in the protect
level will be enabled.
Note (1) If the Write Variable operation command is used to write the wrong pass-
word to the Move to Protect Level parameter after the correct parameter
has been written, the Move to Protect Level parameter will be displayed
and any Write Variable operation commands to write parameters in the
protect level will result in operation errors.
(2) If a password is not set or if it is set to 0, the display will change to the
Operation/Adjustment Protect parameter and writing the parameters in
the protect level will be enabled immediately.
