9.36 1606 An inp 1Xoffset tune BIT 0 0 1 RWZ
9.47 1656 An inp 2Xoffset tune BIT 0 0 1 RWZ
Self-tuning command for the offset of the relative analog input of the expansion card.
Automatic ne tuning of the input. To perform self-tuning, set the input signal to its
minimum value and execute the command.
The conditions containing an offset can be compensated. When this command is sent,
An inp xX offset tune is automatically selected so that the available input signal cor-
responds to the zero value of the variable.
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 higher than 1V, the Value too low alarm is
generated.

9.37 1608 An inp 1X gain tune BIT 0 0 1 RWZ
9.48 1658 An inp 2X gain tune BIT 0 0 1 RWZ
Self-tuning command for the relative analog input gain. Automatic ne tuning of the
input. When this command is sent, Analog inp 1 gain x is automatically selected so
that the available input signal corresponds to the maximum value of the variable.
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 found is automatically accepted even for negative
polarity.
Note! If necessary, the value obtained automatically can be changed manually via Analog inp Xx gain.
To perform self-tuning, set the input signal to its maximum value and execute the com-
mand. A multiplier factor is calculated to apply to the input signal value (not consider-
ing the Analog inp scale parameter) to reach the full scale value.
If the voltage setting on the analog input is less than 1V, the Value too low alarm is
generated.

Setting of the upper speed reference limit as a function of the voltage (or current) of
the relative analog reference of the expansion card.
