The CPU calculates motion tasks in "slices" or segments of 10 ms. As one slice is being

executed, the next slice is waiting in the queue to be executed. If you interrupt the motion

task on an axis (by executing another new motion task for that axis), the new motion task

may not be executed for a maximum of 20 ms (the remainder of the current slice plus the

queued slice).

Configuration of the axis

STEP 7 provides the configuration tools, the commissioning tools, and the diagnostic tools

for the "Axis" technological object.

The PTO requires the internal functionality of a high-speed counter (HSC). This means the

corresponding high-speed counter cannot be used elsewhere.

The assignment between PTO and HSC is fixed. When PTO1 is activated, it will be

connected to HSC1. If PTO2 is activated, it will be connected to HSC2.

You cannot monitor the current value (for example, in ID 1000) when pulses are occurring.
