6.22.4 Magnitude of frequency change setting (Pr. 295)
When setting the set frequency with the setting dial, frequency changes in 0.01 Hz 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.
The above parameter can be set when Pr. 160 "User group read selection" = 0.
The above 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".

Example
쑴
When "1.00 Hz" is set in Pr. 295, one click (one dial gauge) of the setting dial changes the frequency
in increments of 1.00 Hz -> 2.00 Hz -> 3.00 Hz.

NOTES 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. There-
fore, 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. There-
fore, the minimum varying width is 1 even when Pr. 295 < 1.
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 10 Hz increments. Note the excess speed (in potenti-
ometer mode).

One rotation of the setting dial equals to 24 clicks (24 dial gauges).
