4.3.3     Torque reference update rate

The normal update rate for the torque reference (Pr 

4.08

) is 4ms, 

however it is possible to reduce the sample time to 250

μ

s by selecting 

the reference from particular sources, but only in closed-loop vector or 
servo modes. The fast update rate is only possible provided the 
conditions given below are met.

Analog inputs 2 or 3 on the drive

The analog inputs must be in voltage mode with zero offset.
