Analog Outputs 2-21
Analog Outputs Explanation
Each drive has one or more analog outputs that can be used to annunciate a
wide variety of drive operating conditions and values.
The user selects the analog output source by setting [Analog Out Sel].
Configuration
The PowerFlex 70 standard I/O analog output is permanently configured as
a 0-10 volt output. The output has 10 bits of resolution yielding 1024 steps.
The analog output circuit has a maximum 1.3% gain error and a maximum 7
mV offset error. For a step from minimum to maximum value, the output
will be within 0.2% of its final value after 12ms.
The PowerFlex 700 standard I/O analog output is permanently configured
as a 0-10 volt output. The output has 10 bits of resolution yielding 1024
steps. The analog output circuit has a maximum 1.3% gain error and a
maximum 100 mV offset error. For a step from minimum to maximum
value, the output will be within 0.2% of its final value after 12ms.
Absolute (default)
Certain quantities used to drive the analog output are signed, i.e. the
quantity can be both positive and negative. The user has the option of
having the absolute value (value without sign) of these quantities taken
before the scaling occurs. Absolute value is enabled separately for each
analog output via the bitmapped parameter [Anlg Out Absolut].
