Setting from the operation panel
5.20.3 Magnitude of frequency change setting (Pr. 295)
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 167)
This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write
selection.
(1) Basic operation
When a value other than "0" is set in Pr. 295, the minimum varying width when the set frequency is changed by the setting dial
can be set.
For example, when "1.00Hz" is set in Pr. 295, one click (one dial gauge) of the setting dial changes the frequency in
increments of 1.00Hz→2.00Hz→3.00Hz.
∗One rotation of the setting dial equals to 24 clicks (24 dial gauges).
When setting the set frequency with the setting dial, frequency changes in 0.01Hz increments in the initial status.
Setting this parameter increases the magnitude of frequency which changes according to the rotated amount of the
setting dial, improving operability.

REMARKS
When machine speed display is selected with Pr. 37, the minimum increments of the magnitude of change is 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.
When the set frequency (speed) is 100 or more, frequency is displayed in 0.1 increments. Therefore, the minimum varying
width is 0.1 even when Pr. 295 < 0.1.
When the machine speed setting is 1000 or more, frequency is displayed in 1 increments. Therefore, the minimum varying
width is 1 even when Pr. 295 < 1.
NOTE
For Pr. 295 , unit is not displayed .
This parameter is valid only in the set frequency mode. When other frequency-related parameters are set, it is not
activated.
When 10 is set, frequency setting changes in 10Hz increments. Note the excess speed. (in potentiometer mode)
