LA - Analog I/O Parameters
Analog Input 1 Scaling
With parameters LA05-07 or LA15-17, the corresponding analog input
signals can be adapted in X and Y direction as well as in the gain. The
input value corresponds to the applied analog voltage. The output value is
what is processed by the drive, calculated according to following formula:
Out = Amplification x (In - X Offset) + Y Offset
The analog pattern can be scaled directly through this parameter. As an
example, if the analog signal is +/- 0...5 V, the pattern gain can be changed to
2.00 to provide full scale control of the motor speed at +/- 0...10 V.
