Remark: For the DSCDP and DSCDL, if parameter K150, K151 or K158 is modified, the SAV command
must be executed on both axes.
These 3 registers allow the user to define the 'non-rectified source signal'.
It is possible to modify the offset and the amplitude of the source register signal with the MOF and MAM
commands both the alias of the parameters K154 and K155.
Remark: For the DSCDP and DSCDL, if parameter K156 or/and K157 is modified, the SAV command must
be executed on both axes.
The MAM alias use the same syntax than parameter K155. Refer to §6.3
for more information
about the syntax and the possible operators.
The output voltage of the analog output is included between +20V and –20V between XAOUT+ and XAOUT-:
+20V corresponds to -8192 increments and -20V to 8191 increments.
Here is the formula giving the rectified source register signal value from the non-rectified value:
From this point, the 'source register' mode is identical to the 'direct' mode described in the previous chapter.
The digital analog converter (DAC) may induce a small offset and amplitude error. These errors can be
removed with the DAO (DAc Offset) and DAA (DAc Amplitude) commands.
