Function
By changing the setting of
H
, the function of the VI/S3 terminal can be switched
between 0~(5)10Vdc voltage input and 4~20mAdc current input.
The
H
to
H
parameters are used to adjust the output frequency according to the
analog signal (voltage: 0~(5)10Vdc, current: 4~20mAdc) from an external device.
