4.2.24 Parameter write disable selection (Pr. 77)
Pr. 77 "parameter write disable selection"
You can select between write-enable and disable for parameters. This function is used
to prevent parameter values from being rewritten by incorrect operation.

Parameter values may only be written while the inverter is at a stop in the
PU or CC-Link operation mode. (Note 1)
2 Write enabled even while the inverter is running.
Note:1. The parameters half-tone screened in the parameter list can be set at any
time.
2. If Pr. 77 = 2, the values of Pr. 23, Pr. 66, Pr. 71, Pr. 79, Pr. 90, Pr. 96,
Pr. 180 to Pr. 183 and Pr. 190 to Pr. 192 cannot be written during operation.
Stop operation when changing their parameter settings.
3. When the parameter unit (FR-PU04) is used, setting "1" in Pr. 77 can inhibit
parameter write. At this time, values may be written to Pr. 75, Pr. 77 and
Pr. 79.
Parameter clear and parameter all clear are also be inhibited.
