* 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.
Command voltage
The command voltage of the analog inputs always follows the formula below:
V
input
= (AI+) - (AI-)
