For
testing the DAC |
If the axis is aborted or all PID gains are zeroed,
you can use the PIDOutputOffset parameter
to set the DAC voltage directly. (3277 = 1Volt,
6553 = 2Volts, etc.)
You can only use the PIDOutputOffset parameter
if the controller is not configured for motor
commutation. If the controller is configured for
commutation, use the Commutation DAC Offset to
test the DAC.

For
using the DAC as a general purpose analog output |
In some cases, the easiest way for the
host to generate an analog signal is to set all
PID gains to zero and use the PIDOutputOffset
parameter to set the desired voltage level.
Alternatively, you can use the Commutation DAC
Offset for the same purpose, which has the advantage
that the voltage levels can be individually set
for the two DACs.
