5.7.9 Frequency change increment amount setting
When setting the set frequency with the setting dial of the operation panel (FR-DU08), the frequency
changes in 0.01 Hz increments in the initial status. Setting this parameter to increase the frequency in-
crement amount that changes when the setting dial is rotated can improve usability.
Basic operation
When Pr. 295
≠
"0" is set, the minimum increment when the set frequency is changed with the setting
dial can be set.
For example, when Pr. 295 = "1.00 Hz" is set, one click (one dial gauge) of the setting dial changes the
frequency in increments of 1.00 Hz, such as 1.00 Hz
→
2.00 Hz
→
3.00 Hz.

NOTES When machine speed display is selected in Pr. 37 "Speed display", the minimum increments of
change are determined by Pr. 295 as well. Note that the setting value may differ because the
speed setting performs frequency conversion for the set machine speed, and then reverse-con-
verts it to the speed display again.
For Pr. 295, the increments are not displayed.
The Pr. 295 setting is enabled only for changes to the set frequency. It does not apply to the set-
tings of other parameters related to frequency.
When 10 is set, the frequency setting changes in 10 Hz increments. Be cautious of excessive speed
(in potentiometer mode).
