Speed
Example:
The speed reference of a drive is assigned with a max external voltage of 5V. With this value the drive must
reach the maximum speed allowed (set using Full scale speed ).
As the Analog inp x scale parameter a scale factor of 2 is entered (10V : 5V)
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
14.4 1506 An inp 1 offset tune BIT 0 0 1 RW VS
14.20 1556 An inp 2 offset tune BIT 0 0 1 RW VS
Self-tuning command for the relative analog input offset. Automatic fine tuning of the input. To perform self-
tuning, set the input signal to its minimum value and execute the command. The conditions containing an off-
set can be compensated. When this 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 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.
Menu PAR Description UM Type FB BIT Def Min Max Acc Mod
14.5 1508 An inp 1 gain tune BIT 0 0 1 RW VS
14.21 1558 An inp 2 gain tune BIT 0 0 1 RW VS
Self-tuning command for the relative analog input gain. Automatic fine tuning of the input. When this com-
mand 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 that is found is automatically accepted for the other direction of rotation.
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 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 Value too low alarm is generated.
