Homing methods 11-14: Reference cam, zero pulse and negative limit switch

Method 11

• Reverse direction after active reference cam. The zero corresponds to the first zero pulse after a falling edge.
• Zero at first zero pulse after falling edge of reference cam.
• The reference cam must be overrun, then the first zero pulse corresponds to the zero.

Method 12

• Zero corresponds to first zero pulse with active reference cam.
• Reverse direction after falling reference cam edge. The zero point corresponds to the first zero pulse after the rising edge of the reference cam.
• Reverse direction when reference cam has been overrun. The zero corresponds to the first zero pulse after the rising edge.

Method 13

• Reverse direction when reference cam has been overrun. The zero corresponds to the first zero pulse after the rising edge.
• Reverse direction when reference cam becomes inactive. The zero corresponds to the first zero pulse after the rising edge.
• Zero corresponds to first zero pulse with active reference cam.

Method 14

• Zero corresponds to first zero pulse after running over reference cam.
• Zero corresponds to first zero pulse after falling edge of reference cam.
• Reverse direction after active reference cam. The zero corresponds to the first zero pulse after a falling edge.
