9.2.15 Setting Frequency Command on Frequency Monitor
 How to adjust the frequency command by the keypad while monitoring the output frequency on
the keypad?
 When the "Enable frequency changes through monitor display [b163]" is set to "Enable (01)" and
the "Frequency command selection [A001]
*1
" is set to "Parameter setting (02)", the frequency
command can be changed by pressing keys on the keypad while "Output frequency monitor
[d001]" or "Output frequency scale conversion monitor [d007]" is displayed as long as the
inverter is running.
 After changing the frequency command, pressing the [SET] key saves the new frequency
command value in the inverter memory.

 Please note that if the "FUP/FDN data save enable [C101]" is set to "Save (01)", the frequency
command value that was changed using [d001]/[d007] is saved in the inverter memory when
the power is shut off.
 This function cannot be used during PID operation or when the inverter is stopped.
 Since this function overwrites the "Output frequency setting or monitor [F001]" setting while
displaying [d001]/[d007], there may be a time discrepancy between the key operation and the
display depending on the acceleration/deceleration time setting.
