 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.

*2 Writing during operation is disabled. To change the parameter setting value, stop the operation.
 Disabling parameter write (Pr.77 =
"1")
• Parameter write, Parameter clear, and All parameter
clear are disabled. (Parameter read is enabled.)
• The following parameters can be written even if Pr.77 =
"1".
