Description
IN-16 V1 Inverting
Inverts the direction of rotation. Set this code to “1 (Yes)” if you need the motor
to run in the opposite direction from the current rotation.
IN-17 V1
Quantizing
Quantizing may be used when the noise level is high in the analog input (V1
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 IN-07 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 maximum analog
input (60 Hz), the output frequency will increase or decrease by 0.6 Hz for
every 0.1 V change in voltage.
When the analog input is increased, an increase in 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 (ripples).
