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 provided 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
