6.6.4 Fine adjustment of frequency setting signal
: VI voltage bias
: VI voltage gain
Function
These parameters are used to fine adjust the relation between the frequency setting signal input
through the analog input terminal VI and the output frequency.
Use these parameters to make fine adjustments after making rough adjustments using the
parameters
f201 to f204.
The figure below shows the characteristic of the frequency setting signal input through the VI terminal and
that of the output frequency.
* Bias adjustment of VI input terminal (
f470)
Decrease the value in case frequency is output even though the frequency command is 0 (zero) Hz.
* Gain adjustment of VI input terminal (
f471)
Increase the value in case the output frequency doesn’t reach the maximum frequency even though the
maximum voltage and current are applied.
