It is possible to scale AO1 to AO4 with 2 parameters each:
− the range of each AO is set by means of ConvModeAO1 (15.03) to ConvModeAO4 (15.18)
− if the range is set to bipolar or unipolar signals with offset, ±100 % of the input signal connected to an AO
is scaled by means of ScaleAO1 (15.05) to ScaleAO4 (15.20)
− If the range is set to unipolar signals without offset, only +100 % of the input signal connected to an AO is
scaled by means of ScaleAO1 (15.05) to ScaleAO4 (15.20). The smallest value is always zero.
− It is possible to invert the AO’s by simply negate IndexAO1 (15.01) to IndexAO4 (15.16)
Example:
− In case the min. / max. voltage (±10 V) of AO1 should equal ±250 % of TorqRefUsed (2.13), set:
1. IndexAO1 (15.01) = 213
2. ConvModeAO1 (15.03) =
±
10V Bi
3. ScaleAO1 (15.05) = 4000 mV
