Understanding the Scale and Offset Parameters for Input
Analog Input 1 and Analog Input 2 are used in explaining the scale
and offset parameters. At Analog Input 1, between TB21 terminals 9
and 10, a potentiometer with a range of ±10V
DC has been
connected. Analog Input 1 has been linked to Velocity Reference
(parameter 101) in the drive, which gives the potentiometer control
of the external velocity reference.
To calibrate the pot to control 100% base speed in both directions,
you need to adjust the scale parameter. The default value of the scale
parameters allows a total range of 4096, –2048 to +2048. This
allows only 50% base speed in each direction. By setting a scale
factor of 2 in Analog Input 1 Scale, the digital input is multiplied by
2. This provides a range of ±4096, or 100% base speed in both
directions.
If you want a range of ± 2 times base speed, the scale factor would
be 4 (base speed is 4096, 2 times base speed is 8192, 2048 times 4 is
8192). Analog Input 1 Offset remains at the default value of zero,
allowing the input range to be ±10V. The range of the offset
parameter is ± 20V
DC as shown in Figure 2.1.

For Analog Input 2, a 0 to 10 volt potentiometer is used to adjust the
Torque Reference from –100% to +100%. To do this, you need to
adjust both the scale and offset parameters. By linking Analog Input
2 to Torque Reference (parameter 162), the potentiometer connected
to Analog Input 2 becomes the Torque Reference Signal. This signal
must be scaled and offset to get the entire ±100% in the 0 through 10
volt range. A digital range of 8192 (±4096) must now be scaled for
an analog range of 10 volts, and must be offset so 5 volts on the
potentiometer indicates 0% Torque.
