Altivar 61 AO feedback need help

[PLC_L]

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%

The range of the AO in the drive is 0 - 2 *In

So if on the drives nameplate its rated for 50A, then the range in your plc should be 0-100 or 0-1000 for better resolution
