PTOs

High-speed 5 V differential signals (A+/A-, B+/B-, Z+/Z-) and open collector (zero pulse) are
supported.

Analog inputs/outputs (AIs/AOs)

4.3.3.1

AIs

SINAMICS V90 has two analog input terminals. The input voltage at each analog input
varies with control modes.
Pin No.
19, 20
21, 22
* If the AI input voltage 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
3600 rpm at 12 V.
