How is the value of motor torque (OTR) obtained in the ATV320 drive?

Issue:   
Needs to know the motor torque (OTR) on an ATV320 drive
 
Product Line:   
ATV320
 
Environment:  
All
 
Cause:   
Wants to know how motor torque monitoring is achieved. Is it measured or estimated
 
Resolution:   
On ATV320, this parameter will be estimated (the torque is estimated based on motor current measured).
The torque of motor is not measured by the drive. It is calculated from the measurement of motor
current.
OTR = (Iq / Iqn) * (PhirdRef / Phirn) in %
With: Iq : Current torque provide by the command to drive motor
 PhirdRef : Flux provide by the command to drive motor
 Iqn : Nominal Current torque compute with the motor name plate
 Phirn : Nominal flux of the motor
