5.4.13 Parameter write selection
Whether to enable the writing to various parameters 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.)
 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.
