Communications Operation Command to Move to the Protect Level
• The Write Variable operation command can be used via communications 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.
Note1: If the Write Variable operation command is used to write the wrong password 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.
