14.3.4. Conveyor Calibration
Set the home offset of the station within the conveyor and the offset between stations. And
teach the locations of the stopper and the work sensor within the station to measure the
information necessary for loading and unloading the PCB.
Calibration is made upon initial installation of the machine. The recalibration of transport
rail should be performed when mechanical adjustments to the transport rail occur.
