Issue:
Analog input resolution bit size on the ATV32 and ATV320 Drives using ATV logic
Product Line:
ATV32 and ATV320 drives
Environment:
All
Cause:
Analog input bit size resolution.
Resolution:
All the analog signals are represented internally in ATV32/ATV320 ATVLogic as 13-bit (0..8192) + 1 bit for sign.
Below some example of AIx type and correspondence with value read by ATVLogic:
If AIx is 0..20mA type :
-> "0" read by ATLogic will correspond to 0mA.
-> "4096" read by ATLogic will correspond to 10mA.
-> "8192" read by ATLogic will correspond to 20mA.
If AIx is 4mA..20mA type :
-> "0" read by ATLogic will correspond to 4mA.
-> "4096" read by ATLogic will correspond to 12mA.
->"8192" read by ATLogic will correspond to 20mA.
If AIx is 0V..10V type :
-> "0" read by ATLogic will correspond to 0V.
-> "4096" read by ATLogic will correspond to 5V
-> "8192" read by ATLogic will correspond to 10V.
If AIx is -10V..10V type :
-> " - 8192" read by ATLogic will correspond to -10V.
-> "0" read by ATLogic will correspond to 5V
-> "8192" read by ATLogic will correspond to 10V.
