oltage is higher than 10 V, the speed is not limited to the value at 10 V (p29060), but
scaled according to p29060. For example, if p29060 = 3000 rpm, the speed is 3300 rpm at 11 V and
The command voltage of the analog inputs always follows the formula below:
V

= (AI+) - (AI-)
The SINAMICS V90 has two analog outputs. You can find detailed information about these
two analog outputs from the table below:
Analog output 1 for monitoring
Analog output 2 for monitoring
Two parameters, p29350 (selects signal sources for AO1) and p29351 (selects signal
sources for AO2), are used to select the source of analog output:
p29350
