command is sent, An inp x offset tune is automatically selected so that the available
input signal corresponds to the zero value of the variable. Offset tuning can also be
performed with the drive enabled. Automatic tuning can only be performed if the fol-
lowing condition is present:
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 Analog inp x
offset .
If the voltage setting on the analog input is higher than 1V, the Value too low alarm is
generated.

Self-tuning command for the relative analog input gain. Automatic fine tuning of the in-
put. 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. Offset
tuning can also be performed with the drive enabled.
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 x 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.

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.

the relative analog reference.
