Analog and Sometimes it is helpful to be able to quickly convert between the voltage or current
Digital Value signal levels and the digital values. This is especially useful during machine startup
Conversions or troubleshooting. The following table provides formulas to make this conversion
easier.
Voltage
Range
0 – 5V
0 – 10V
$ 5V
$10V
For example, suppose you are using the
$
of –2047 to +2047. If you know you need
a –3V signal level, just insert these
numbers into the appropriate formula
from the table. It will give you the digital
value to store in the V-memory location
containing the output data.
