Actual current value MCTRL-I-ACT is displayed time-delayed

Question:
Why is the actual current value MCTRL-I-ACT displayed with a time-delay of some ms, e. g. in case of the internal oscilloscope?

Answer:
The internal signal MCTRL-I-ACT is calculated by means of several measured actual current values. The calculation is effected in a cycle more slowly in order to increase the CPU time utilization not more than necessary.
This is the reason why the current actual value display shows a time-delay and comparatively high fluctuations.

Maybe the signal 'MCTRL-MSET2' can be used for detecting the load condition of the motor. This signal is generated in the cycle of 1 ms.
