8.7
Frequency change increment amount setting
(standard model)
When setting the set frequency with the setting dial of the operation panel, the frequency changes in 0.01 Hz increments in the
initial status. Setting this parameter to increase the frequency increment amount that changes when the setting dial is rotated
can improve usability.
 Basic operation
• When Pr.295 ≠ "0", the minimum increment when the set frequency is changed with the setting dial can be set.
For example, when Pr.295 = 1.00 Hz, 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.
NOTE
• When machine speed display is selected in Pr.53 Frequency / rotation speed unit switchover , the minimum increments of
change are determined by Pr.295 as well. Note that the setting value may differ as speed setting changes the set machine
speed and converts it to the speed display again.
• For Pr.295 , the increments are not displayed.
• The Pr.295 setting is enabled only for the changes to the set frequency. It does not apply to the settings of other parameters
related to frequency.
• When 10 is set, the frequency setting changes in 10 Hz increments. Be cautious of excessive speed (when Automatic
frequency setting enabled).
