Analog outputs
ANOUT 3 / 4, PWM outputs
Process variables that change only slowly e.g. the power module temperature, can be output via two virtual
analog outputs (ANOUT3 and 4). This is realized by generating a PWM signal (pulse width modulation) on a
digital output. The period T is adjustable with parameter An.46 or An.52 "ANOUT period" of 1 ...240 s.

3.3.3 Analog output / display (ru.33...34)
The following parameters are used to display the analog outputs, before and after the characteristic amplifier:
ru.33 ANOUT1 / pre ampl. display
ru.34 ANOUT1 / post ampl. display
3.3.4 ANOUT 1 Function (An.31 / An.36 / An.41, An.47)
These parameters define the process variable, which controls the respective output.Following adjustments
are possible:
Value Function
2 Actual line frequency (ru.03)
5 Reference DC voltage (ru.18)
6 DC current (ru.15)
7 AC current (ru.17)
8 Digital with An.32 / 42 / 48
12 Power module temperature (ru.38)
26 Actual power (ru.81)
Not listed values are not assigned.
