As shown in Figure 2.2, the offset voltage adds the corresponding
digital value to the range. In this case, an offset of –5 volts adds a
digital value of –1024 to the range. This causes 0 volts on the
potentiometer to register as –1024 digital internal to the drive and 10
volts on the potentiometer will be +1024 to the drive. This can then
be scaled by a factor of 4 (8192 drive units) so that 0 volts sends a
digital value of –4096 for –100% torque, and 10 volts sends a digital
value of +4096 for +100% torque.

Understanding the Scale and Offset Parameters for Output
Analog outputs are similar to analog inputs. Each output has a scale
and offset parameter, along with a specific variable parameter used
for linking. Differences occur because of the direction of
information flow. The drive sends a digital value in drive units,
which must be matched to the voltage of the monitoring device.
Similar to analog inputs, the analog output converts a ±2048 value to
±10V DC. Thus, when the drive sends ±100% base speed (equal to
±4096), it must be scaled by 0.5 to be in the proper range (±4096 ×
0.5 = ±2048). The offset can be ±20V DC, even though the physical
limit is ±10V
dc. This allows you to offset the signal anywhere
within the entire range.
In Figure 2.3
, Analog Output 1 is used as an example to show the
scale and offset parameters. At Analog Output 1, a meter with a
range of 0 through 10V DC has been connected. Analog Output 1
has been linked to Velocity Feedback (parameter 269).
