ATV320 current/torque scalling

[BertrandR]

Hello, 

I am working with an ATV320 with embeeded logic.

The ATV is for 7,5KW motor but for test purpose, I wired a 2.2KW motor 

I adapt parameters ( nominal current NCR set at 4,6A ....)

Even with no load, with a current measurement around 2.3A, the current monitoring give me more than 100%.

The result in ATV logic is the value is 4096 ( I guess limit of the 12bits conversion).

I missed something but no idea what.

Thanks you for your help if you have any idea.

For admin : Label choice are too few 😉

When current is too high with the small motor, it may be a saturation, (in fact the voltage frequency law is too high). Could be possible to lower it as shown in the user's manual (setting UFR, also motor control type Ctt (should be "std". This ratio can be changed on UFr value (you should decrease this value). Also one important topic, when you have entered all your motor data, I advise you to make the motor tuning. this action will allow the drive to better analyse the motor.... Thank you to let me know.

Thank you for your help. I will check once again, do a motor tuning and revert to you for feedback.
