Method 28: Homing on Origin Switch (Negative Direction, Positive
Edge)
Home Switch
Negative Limit Switch
Figure 4.15: Homing Method 28
Initial movement direction of this origin search method is Negative Direction and movement velocity is the value
of Speed during search for switch (6099h, index 01h). Negative Limit Switch goes ON, it goes to opposite
direction. If Origin Switch goes ON, it goes out of Origin Switch toward opposite direction by velocity of Speed
during search for zero (6099h, index 02h). If it gets out of Origin Switch, it searches Origin Switch again by velocity
of Speed during search for zero (6099h, index 02h) , then stops when it goes ON then set correspondent position
as sensor origin position.
Method 33, 34: Homing Index Pulse
Index Pulse
Figure 4.16: Homing Method 33
Origin search method 33 is to move from current position to Negative direction, 34 is moving to Positive Direction
and movement velocity is Speed during search for zero (6099h, index 02h). Index Pulse goes ON then stops then
set correspondent position as sensor origin position.
Method 35: Set the current position origin
This origin search method is to set current position as sensor origin position. If set value of Home offset (607Ch)
is not 0, it moves to correspondent position.
