Homing methods 7 to 10:

Method 7: Reference cam, zero pulse and positive limit switch

• The start movement is in the direction of the positive (right) hardware limit switch. It and the reference cam are inactive.
• The direction is reversed after an active reference cam. The zero corresponds to the first zero pulse after a falling edge.
• The start movement is in the direction of the negative (left) hardware limit switch. The reference point is set at the first zero pulse after a falling reference cam edge.
• The first zero pulse after overrunning the reference cam corresponds to the zero point.

Method 8:

• The zero corresponds to the first zero pulse with an active reference cam.
• At a falling reference cam edge the direction changes. The zero point corresponds to the first zero pulse after the rising edge of the reference cam.
• The direction reverses if the reference cam has been overrun. The zero corresponds to the first zero pulse after the rising edge.

Method 9:

• The direction changes when the reference cam becomes inactive. The zero corresponds to the first zero pulse after the rising edge.
• The zero corresponds to the first zero pulse with an active reference cam.

Method 10:

• The reference cam is overrun and the first zero pulse after the falling edge corresponds to the zero point.
• After a falling reference cam edge: The first zero pulse corresponds to the zero point.
• After an active reference cam: The zero corresponds to the first zero pulse after a falling edge.
