1. CENT motor stop signal trigger generation timing
2. IN motor start trigger generating timing (when transporting PWBs from the IN buffer to center buffer)
1. Severe collision of the PWB with the stopper due to insufficient deceleration of PWB. (Solution: Make the value smaller
than 8, which, however, results in further beyond the stopper frame.)
PWB failing to reach the stopper due to excessive deceleration. (Solution: Make the value larger than 8.)
2. Increased PWB transport tact time due to delayed starting of IN motor.

With the reference pin in 1.5 0/-0.5 mm lowered position, loosen the adjusting screw and move the sensor bracket up and
down to activate the sensor; then, at that point, secure the sensor bracket in position.
1. The sensor is to be activated when the reference pin lowers 1.5 0/-0.5 mm.

1. Detects that the centering pin does not fit into the reference hole.
1. The centering pin does not fit into the reference hole, which means that the components are transported with the PWB
incorrectly positioned, resulting in the components being placed at wrong positions.

Mount a dial indicator to camera bracket D of the head. When the measurement point indicated below of transport rail F
becomes parallel with X-axis to //|0.1, tighten base bar B set screw (SL6104042TN).

1. Matches the placer coordinate axis with the transport direction.
1. The position of the head in X-direction determines deviation of the transport unit from the PWB in Y-direction, resulting in
variations in placement positions.
