Use the Evaluation > Remove Oversampling… command to remove the intermediate values from curves with oversampling. Enter the actual cycle time for this channel. The unnecessary intermediate values are then removed.
Oversampling occurs when a curve is sampled at a higher sampling rate than the cycle time valid for the curve. Since this results in the same value being sampled repeatedly, unnecessary intermediate values are saved. This leads to undesirable zero points when a curve is differentiated.
Differentiating a curve
Keep in mind that this command cannot be undone.
On the iTNC 530, a possible oversampling is already filtered out during recording with TNCscope. For NCK-based controls from milestone 15 onwards, there is no longer any oversampling during recording.
