What is the maximum torque rating for the ATV630?

Issue:
Torque rating

Product Line:
ATV630

Environment:
All models and serial numbers

Cause:
None

Resolution:
- 110% of maximum continuous current for 60s for ATV600 with DRT=Normal rating , 120% of maximum continuous current for 60s for ATV900 in DRT=Normal rating.
- 150% of maximum continuous current for 60s for ATV 630 and ATV 930, with DRT=High rating. 

The maximum torque of drive, of course more current we have more torque we have but for this depends on :
- For asynchronous the torque performance is link to the efficiency of the motor.
- On permanent magnet there is no over torque capability, 120% of over current will reach 120% of over torque ( 1.2Cn).

For example with ATV71 its 165 % of over current we can reach 2,2 Cn. Then with 120% of overcurrent we can reach 1.6 Cn (but not with all motor).
