6.15 Zero pulse test
To enable evaluation for the zero pulse test, P 541/P 571 = 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 high until the
next zero pulse appears. Conversely, the measurement variable remains low until
another zero pulse appears. Bear in mind that the pulse width of the scope signal
does not match the pulse width of the actual zero pulse.

NOTE
l
When in zero pulse test mode, zero pulse evaluation will
not
be
available during homing.
l
Regardless of this
, all zero pulse events will be counted. The
zero pulses are counted by counter evaluation
