Description: The voltage output daughter board returns axis parameter
ATYPE
of 6.
The Analog Output Daughter board provides a 12 bit +/-10v voltage output for
driving inverters and other devices. The board is a simplified servo daughter
board and the connections are similar. The encoder port does not function even if
the connector is fitted.
Voltage Output
The +/-10v output voltage to drive external servo amplifiers is generated
between the V+ and V- pins. The voltage output is isolated and floating but if
multiple daughter boards are fitted it should be noted that the boards share a
common power supply for generation of the +/-10v. This means that the V- pins
should not be referenced to different external voltages.
The board functions like a servo daughter board with the SERVO= OFF the value in
the axis parameter DAC is written to the 12 bit digital to analog converter.
Therefore:
Note: The daughter board hardware inverts the voltage relative to the DAC parameter.
V V + -
>>DAC=2047
This will set -10volts on voltage output
>>DAC-0
This will set 0volts on voltage output
>>DAC=-2048
This will set +10volts on voltage output
