Parameter instruction code list
The parameter numbers in parentheses are those for use with the parameter unit (FR-
PU04).
* Though parameter setting by RS-485 communication can be made in the setting
increments indicated in the table, note that the valid setting increments are as
indicated in the parameter list (page 58).
