In ACS355 drives, can I get estimated motor's torque data when I use torque control? and how?

Since ACS355 drives apply a sensorless torque control, which means that the torque on the shaft is estimated. I was wondering whether I could get this data from drives.

sure, the drive give you - reading  parameter 105 (only read value) -  the estimated used torque in %.

For example using the AO referred to the torque,  you can "read" by one external device the torque value.

Or, if you use one fieldbus, at the same time you can transfer the value to one master.

Hope this help you

Hi Flavio,
Thank you so much for your answer!
May I ask another question?
Since what I can get from AO is a current value, what kind of device can be used to display this current value from AO?
Thank you so much for your help!
Best wishes,
Ruiying Wu

Each type of analogue indicator that have input signal from 0 to 20 mA

It is really helpful, since I am still studying in school, only know multimeter can measure dc current. Thank you so much for your help!
