Hi all sifu,
I'm facing a problem recently when trying to retrieve the atv61 drive current feedback via its AO1 output in mA when the drive is in running. The plc using is m340 and I'm configured a bmxami0800 module for this purpose. All the while I was thinking those AO feedback from the drive are all very straightforward but don't seems so when I deal with motor current. The reading I get in the plc totally not tally with the monitoring drive current on the hmi during running. im quite puzzled with the statement below which found from the manual, so I believe there must be some calculation in between, appreciate if any expert willing to enlighten .
[I motor] (OCr): Current in the motor, between 0 and 2 In (In = rated drive current indicated in the
Installation Manual and on the drive nameplate).
Plc analog input conversion
AI LEU : 0
AI HEU : 100 (had tried change this to 52.8 but also not tally)
AI lo_raw : 0
AI hi_raw : 10,000
Atv61 drive setting
Rated mot. Current : 52.8A
AO1 : I motor
AO1 min output : 4mA
AO1 max output : 20mA
Scaling AO1 min : 0%
Scaling AO1 max : 100%
