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.
About 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 using  (initial up/down frequency).
About the change of the initial up/down frequency
To make the inverter automatically save the frequency immediately before it is turned off and start
operation at that frequency next time power is turned on, set  (change of initial up/down
frequency) to 1 (which changes the setting of  when power is turned off).
Keep in mind that the setting of  is changed each time power is turned off.
Frequency adjustment range
The frequency can be set from 0.0Hz to  (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  (Frequency free unit magnification) is set to 1.00, the output frequency can be adjusted in
steps of 0.01Hz.
