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 250μs 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
