ADL300 • Functions description and parameters list 57
Automatic tuning can only be performed if the following condition is present:
- Input voltage less than 1V or input current less than 2 mA
NOTE! The value that is obtained automatically can be changed manually, if necessary, using An inp offset xX.
If the voltage setting on the analog input is more than 1V the “Input value too high” message is displayed.

12.5 1608 An inp 1X gain tune BIT 0 0 1 ERW FVS
12.17 1658 An inp 2X gain tune BIT 0 0 1 ERW FVS
Self-tuning command for the relative analog input gain. Automatic ne tuning of the input. When this command is sent,
An
inp XX gain tune
is automatically selected so that the available input signal corresponds to the maximum value of the vari-
able.
Two conditions are necessary in order to perform automatic tuning:
- Input voltage greater than 1V or input current greater than 2 mA
- Positive polarity. The value that is found is automatically accepted for the other direction of rotation.
Note! If necessary, the value obtained automatically can be changed manually via An inp XX gain tune.
To perform self-tuning, set the input signal to its maximum value and execute the command. A multiplier factor is calculated
to apply to the input signal value (not considering the Analog inp scale parameter) to reach the full scale value.
If the voltage setting on the analog input is less than 1V the “Input value too low” message is displayed.

12.18 1660 Analog inp 2X filter ms UINT16 10 2 100 ERW FVS
Filter on the measurement of the corresponding analog input. This parameter can be used to control the response of the
analog input and reduce any possible noise and interference.
