<<Sample sequence diagram 2: Adjustment with pulse signals>>
 If two signals are impressed simultaneously
 If a clear single and an up or down signal are impressed simultaneously, priority will be given to the
clear signal.
 If up and down signals are impressed simultaneously, the frequency will change at the specified up
or down rate.
 The setting of the initial up/down frequency
To adjust the frequency starting at a specified frequency other than 0.0 Hz (default initial frequency)
after turning on the inverter, specify the desired frequency by setting the parameter f268 (initial
up/down frequency). Also, set f269 (change of initial up/down frequency) to 0 (Not changed).
 The change of the initial up/down frequency
To make the inverter automatically save the frequency immediately before the power is off and start
operation at that frequency next time power is on, set f269 (change of initial up/down frequency) to
1 (which changes the setting of f268 when power is turned off).
Keep in mind that the setting of f268 is changed each time power is turned off.
 Frequency adjustment range
The frequency can be set from ll (lower limit frequency) to fh (Maximum frequency). The lower-limit
frequency will be set as soon as the set frequency clearing function (function number 92, 93) is entered
from the input terminal.
 Minimum unit of frequency adjustment
If f702 (Frequency free unit magnification) is set to 1.00, the output frequency can be adjusted in
steps of 0.01Hz.
