Homing Methods 7…14
Homing methods 7…14 use a home switch that is active over only a portion of
the travel. In effect, the switch has a momentary action as the axis position sweeps
past the switch. Using methods 7…10, the initial direction of movement is
forward and by using methods 11…14, the initial direction of movement is
reverse, except if the home switch is active at the start of motion. In this case, the
initial direction of motion is dependent on the edge being sought. The home
position is at the index pulse on either side of the rising or falling edges of the
home switch, as shown in the following two diagrams. If the initial direction of
movement leads away from the home switch, the drive must reverse on
encountering the relevant limit switch. All of these methods use the fast
acceleration parameter.
