5.3.6 Internal Analogue Output Functions<br />
Ventura Remote PLC has:<br />
� 2 analogue outputs ao0 and ao1<br />
Software<br />
� Analogue outputs send analogue control signals to<br />
drives etc. in order to control and actuate them.<br />
Analogue outputs are designed as PWM outputs.<br />
The voltage is set by the pulse-to-pause ratio plus<br />
subsequent smoothing.<br />
The resolution is used to set the output frequency<br />
and, with it, the range of output voltages:<br />
Resolution<br />
(Aufloesung)<br />
Number of<br />
output values<br />
Frequency<br />
[kHz]<br />
Ripple<br />
8 bit 256 62.5 ±5mV<br />
10 bit 1024 15.625 ±10mV<br />
� To set up the resolution of every analogue output and<br />
to retrieve information about analogue output<br />
variables, choose "Resources, PLC Configuration,<br />
<strong>Kuhnke</strong> Ventura Remote IO CAN (or DP), Internal IO,<br />
AO 2".<br />
