1. Search for stop in the positive direction:
Travel with “Search” speed in a positive direc-
tion until the stop

has been detected.
2. Search for homing point in the negative direc-
tion:
Travel with “Crawl” speed in a negative direc-
tion until the first zero pulse has been detec-
ted. This position is taken as the homing
point.
3. If an axis zero point is parameterised and the
FCT option “Travel to axis zero point after
homing” is activated:
Travel with “Run” speed to the axis zero point.
