Ao.08 V3 Inverting
Inverts the direction of rotation. Set this code to 1 (Yes)
run in the opposite direction from the current rotation.

Quantizing
Quantizing may be used when the noise level is high in the analog input (V
terminal) signal.
Quantizing is useful when you are operating a noise-sensitive system, because it
suppresses any signal noise. However, quantizing will diminish system sensitivity
(resultant power of the output frequency will decrease based on the analog
input).
You can also turn on the low-pass filter using code Ao.03 to reduce the noise, but
increasing the value will reduce responsiveness and may cause pulsations
(ripples) in the output frequency.
Parameter values for quantizing refer to a percentage based on the maximum
input. Therefore, if the value is set to 1% of the analog maximum input (60Hz), the
output frequency will increase or decrease by 0.6Hz per 0.1V difference.
When the analog input is increased, an increase to the input equal to 75% of the
set value will change the output frequency, and then the frequency will increase
according to the set value. Likewise, when the analog input decreases, a decrease
in the input equal to 75% of the set value will make an initial change to the
output frequency.
As a result, the output frequency will be different at acceleration and
deceleration, mitigating the effect of analog input changes over the output
frequency.
