2.15.9.15 Homing Method 17: Homing to Negative Limit Switch (without index pulse)

Method 17 is similar to method 1, except that the home position is not dependent on the index pulse but only on the

negative limit switch translation.

Using this method the initial direction of movement is negative. The home position is the leading edge of the Negative

limit switch.

Axis will accelerate to fast homing velocity in the negative direction and continue until Negative Limit Switch (A1) is

activated (rising edge) shown at position A. Axis then decelerates to zero velocity.

If the negative limit switch is already active when the homing routine commences then this initial move is not

executed.

Axis will then accelerate to fast homing velocity in the positive direction. Motion will continue until the falling edge of the

negative limit switch is detected (position B), where the axis will decelerate to 0 velocity.

Axis will then accelerate to slow homing velocity in the negative direction. Motion will continue until the rising edge of

the negative limit switch is detected (position C), where the axis will decelerate to 0 velocity.

Axis will then accelerate to slow homing velocity divided by 100 in the positive direction. Motion will continue until the

falling edge of the negative limit switch is detected (position 17). This is the home position (excluding offset).
