II input bias

Analog input terminal bias adjustment ([F470], [F472], [F474], [F476], and [F478])
To avoid the influence of noise, there is a tolerance for the minimum input amount so that the inverter starts output after some voltage/current is applied to the analog input terminal by default setting.
To decrease this tolerance value, increase the bias value for a corresponding terminal.
However, if the set value is too large, frequency may be output even when the frequency command is set to 0 (zero).

Analog input terminal gain adjustment ([F471], [F473], [F475], [F477], and [F479])
The set maximum frequency is output before voltage/current reach the maximum value to avoid trouble such as voltage drop by default setting.
When you want to output the set maximum frequency at the maximum voltage and current values, decrease the gain value for a corresponding terminal.
However, if the set value is too small, the maximum frequency may not be output even when voltage and current reach the maximum values.
