Changing the Speed Reference of an IP66, NEMA/UL Type 4X rated
drive
When a Display Group parameter, for example, d001 [Output Freq] is
displayed, and P038 [Speed Ref] is set to A069 [Internal Freq], you can
change the internal frequency using the Up Arrow and Down Arrow
keys.
When the internal frequency is being adjusted, its value is displayed and
the Hertz LED flashes. Any changes are saved immediately. The display
then returns to the Display Group parameter previously shown.
TIP: By default, the speed reference of an IP66, NEMA/UL Type 4X
rated drive is set to the internal frequency, A069
[Internal Freq].
