• Function
It is possible to change the step width changed at panel frequency setting.
This function is useful when only running with frequencies of intervals of 1 Hz, 5 Hz, and 10 Hz units.
Note 1: The settings of these parameters have no effect when the free unit selection (  ) is enabled.
Note 2: Set  to other than 0. When increasing the frequency by rotating the setting dial and if 
(max. frequency) is exceeded by rotating 1 step more, be careful as the  alarm displays before
this happens and the frequency cannot be increased beyond this point.
Similarly, when rating the settings dial to lower the frequency, if the rotating 1 step more lowers it
below  (lower limit frequency), the  alarm displays before this happens and the frequency
cannot be lowered beyond this point.

Operation example

 = 0.00 (disabled)
By rotating the setting dial 1 step, the panel frequency command value changes only 0.1 Hz.
When  = 10.00 (Hz) is set
Rotating the setting dial 1 step changes the panel frequency command value in 10.00 Hz increments, from
0.00 up to 60.00 (Hz).
