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.
