1) Adjustment of 0~10Vdc voltage input
VI terminal • The output frequency
with respect to the
voltage input is adjusted
according to the selected
reference point.

2) Adjustment of 4~20mAdc current input
VI/S3 terminal • The output frequency with
respect to the current input
is adjusted according to the
selected reference point.
• Gradient and bias can be
set easily.
• Set H to  to

3) Adjustment of 0~5Vdc voltage input and external potentiometer (P5-VI/S3-CC)
VI/S3 terminal
* When an external potentiometer is connected to the inverter via the P5V terminal, it is
necessary to set the H (= 47 ~ 50 approx.) a voltage drop might occur,
depending on the resistance of the resistor connected. Therefore, if there is no need
to increase the output frequency above the frequency set with H, use H
for this adjustment.
• The output frequency
with respect to the
voltage input is adjusted
according to the selected
reference point.
• Gradient and bias can
be set easily.
