6. 34. 4 Changing variation steps of panel display
<F707: Step of panel setting>
<F708: Step of panel display>
■ Function
The changeable step width can be 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.
■ Parameter setting
■ Caution when used
The settings of these parameters do not work when <F702: Free unit multiplication factor> is set.
When you set other than "0" to <F707> and increase the frequency by turning the touch wheel to the
right, frequency will not be increased beyond this point and the "HI" message is displayed if the
frequency is over <UL: Upper limit frequency> with just one more step rotation.
Similarly, when you decrease the frequency by turning the touch wheel to the left and if the
frequency falls under <LL: Lower limit frequency> with just one more step rotation, the "LO"
message is displayed in advance and the frequency cannot be lowered beyond this point.
■ Setting example
1) <F707> = not "0.00", <F708> = "0: Disabled"
Under normal conditions, the frequency command value on the operation panel increases by
0.1 Hz when you turn the touch wheel to the right. If <F707> is not "0.00", the frequency
command value will increase by the value with <F707> each time you turn the touch wheel to
the right by 1 step. Similarly, the frequency command value on the operation panel will
decrease by the value set with <F707> when you turn the touch wheel to the left by 1 step.
When the second decimal place of <F707> is 0, the second decimal place of the frequency
command value is not displayed.
2) When <F707> is not "0.00", and <F708> is not "0"
The value displayed on the panel can also be changed in steps.
Output frequency displayed on LCD screen = Internal output frequency x <F708>/<F707>
