8.5.11 Methods (11) to (14): Reference mark, zero pulse
and negative limit switch
8.5.11.1 Method (11)

Reversal of direction of movement after active reference mark. The zero point
corresponds to the first zero pulse after the falling edge.

Zero point at the first zero pulse after falling edge from the reference mark.

Movement must have gone beyond the reference mark, then the first zero
pulse corresponds to the zero point.

8.5.11.2 Method (12)

Zero point corresponds to the first zero pulse if the reference mark is active.

Reversal of direction of movement after a falling edge from the reference
mark. The zero point corresponds to the first zero pulse after a rising edge
from the reference mark.

Reversal of direction of movement when the reference mark has been
passed. The zero point corresponds to the first zero pulse after a rising edge.

8.5.11.3 Method (13)

Reversal of direction of movement when the reference mark has been
passed. The zero point corresponds to the first zero pulse after a rising edge.

Reversal of direction of movement when the reference mark becomes
inactive. The zero point corresponds to the first zero pulse after a rising edge.

Zero point corresponds to the first zero pulse if the reference mark is active.

8.5.11.4 Method (14)

The zero point corresponds to the first zero pulse after crossing the reference
mark.
