Parameter Write Selection; Writing Parameters Only During Stop (Pr.77 = "0" Initial Value) - Mitsubishi Electric FR-F800 Instruction Manual

5.4.12

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.

Parameter write selection
E400
• Pr.77 can be set at any time regardless of the operation mode or operation status. (Setting through communication is unavailable.)
Writing parameters 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.
