Code 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 analog
maximum input (60 Hz), the output frequency will increase or decrease by
0.6 Hz per 0.1 V 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.
