Operation panel FR-DU07
NOTES The number of digits displayed on the operation panel (FR-DU07) is four. Only the upper
four digits of values can be displayed and set. If the values to be displayed have five digits or
more including decimal places, the fifth or later numerals cannot be displayed nor set.
For example: when Pr. 1 is set to 60Hz, 60.00 is displayed. When 120Hz is set, 120.0 is dis-
played. The second decimal place cannot be displayed nor set.
When Pr. 77 (Parameter write selection) = "0" (initial setting), the parameter setting change
is only available while the inverter is stopped under the PU operation mode. To change the
parameter setting independent of the operation status in any operation mode, change Pr. 77
to "2".
