Issue:Analog Input designed for a bipolar -10v to +10v input on the ATV32 drives
Product Line:Altivar ATV32
Environment:All
Cause:AI2 is default for -10v to +10v input.
Resolution:Analog input AI2 is capable of the bipolar input and is factory set as such. Check it by navigated through menus:
ConF - FULL - IO - AI2 -
Parameter AI2t = n10U
Bipolar analog input 0 ± 10 V (maximum voltage ± 30 V)
The + or - polarity of the voltage on AI2 affects the direction of the set point and therefore the direction of operation.• Impedance 30 kÙ
• Resolution: 10 bits
• Precision ±0.5% in 50/60 Hz for 25 °C, ±0.2% in 50/60 Hz for –10 to +60 °C at Äè = 60°C,
• Linearity ± 0.2% (max. ± 0.5%), of max. value
• Sampling time 2 ms
