Parameter write selection
Whether to enable the parameter write or not can be selected. Use this function to prevent parameter values from being
rewritten by misoperation.
• Pr.77 can be set at any time regardless of the operation mode or operation status. (Setting through communication is
unavailable except for the Ethernet communication between the inverter and FR Configurator2.)
 Parameter write enabled only during stop (Pr.77 = "0" (initial value))
• Parameters can be written only during a stop in the PU operation mode.
• The following parameters can always be written regardless of the operation mode or operation status.
*1 Writing during operation is enabled in PU operation mode, but disabled in External operation mode.
