What input is designed for a bipolar -10v to +10v input on the ATV32 drives?
Inputs AI1 and AI2 are both capable of being set up as +10/-10v inputs.
The factory setting for AI1 is n10U (Voltage) which is the only selection shown for AI1t. AI1 is changed to +10v/-10v by going to parameter AI1L under AI1- (AI1 Configuration). Set AI1L to nEG (+/- 100%).
The factory setting for AI2 is 10U (Voltage +/-). It can be changed to a 0-10 volt input by going to parameter AI2t under AI2- (AI2 Configuration). Change AI2t from n10U to 10U (Voltage).
