Zero pulse test

To enable evaluation for the zero pulse test, parameter
P 0541/P 0571 = ON (1) is set. On the oscilloscope it can then be depicted with the measurement variables CH1/3-Np. To make the zero pulse clearly visible, the measurement variable remains at High level until the next zero pulse appears. Conversely, the measurement variable remains at Low level until another zero pulse appears.
In this, the pulse width of the scope signal does not match the pulse width of the actual zero pulse.

NOTE: In zero pulse test mode zero pulse evaluation of homing runs is disabled. Regardless of that, all zero pulse events are counted. The zero pulse test is effected by the counter evaluation P 0411(31) for channel 1 and P 0411(32) for channel 2.
