This example shows that you can have [Analog Out1 Lo] greater than [Analog
Out1 Hi]. The result is a negative slope on the scaling from original quantity to
analog output voltage. Negative slope could also be applied to any of the other
examples in this section.
Example 3 – Signed Output Quantity, Absolute Value Enabled
•
[Analog Out1 Sel] = “Output Torque Current”
•
[Analog Out1 Lo] = 1 volt
•
[Analog Out1 Hi] = 9 volts
•
[Anlg Out Absolut] set so that absolute value is enabled for output 1.
Example 4 – Signed Output Quantity, Absolute Value Disabled
•
[Analog Out1 Sel] = “Output Torque Current”
•
[Analog Out1 Lo] = 1 volt
•
[Analog Out1 Hi] set to 9 volts
•
[Anlg Out Absolut] set so that absolute value is disabled for output 1.
