The following explains the different types of reference travel with different starting points
in the drive using travel diagrams.
Explanation of the reference travel type diagrams
• nRef1 =Reference speed 1
• nRef2 =Reference speed 2
• Starting point of the drive
– [1] Between the reference cam and the right hardware limit switch
– [2] On the reference cam
– [3] Between the reference cam and the left hardware limit switch
• LHWLS = CCW hardware limit switch
• RHWLS = CW hardware limit switch
• CAM = Reference cam
• RefCAM = Reference position cam: Movement to this position takes place when the
argument of the GO0 reference travel command contains CAM.
• RefZP = Reference position zero pulse: Movement to this position takes place when
the argument of the GO0 reference travel command contains ZP.
• RefOffCAM = Reference offset for reference travel with reference position cam CAM
• RefOffZP = Reference Offset for reference travel with zero pulse ZP
• MZP = Machine zero
