A voltage of 0...±11,5 VDC represents the selected size in the range of 0...±115 %
with a resolution of ±10 Bit at the output. 100% correspond to the bracket values
specified in Fig. 6.2.10. In order to be able to balance load-dependent voltage drops,
the limitation at the output of the characteristic amplifiers is ±115 %.

ANOUT2 (X2A.6)
Process variables, that change only slowly, as for example the power module
temperature, can be output over two virtual analog outputs (ANOUT3 and 4). This is
realised through generation of a PWM-signal (pulse-width-modulation) on a digital output.
At that the period T is adjustable from 1...240 s.
