Chapter 5 Solutions for Errors 5-
9
Remove the chip from
the bad chip
discharging conveyer.
Error of the sensor that
detects the discharging
position on the bad chip
discharging conveyer.
Position detection
sensor error
Check the solenoid valve and Air line.
Check the sensor.
Check the solenoid valve and Air line.
Check the sensor.
PCB is present on the
Work 1 conveyer when
homing.
Take out the board and do homing.
PCB is present on the
Work 1
Take out the board and do homing.
PCB is present on the
loading conveyer when
homing.
Take out the board and do homing.
PCB is present on the
exit conveyer when
homing.
Take out the board and do homing.
PCBs are present on the
entrance and Work 1
conveyers when homing.
Take out the board or adjust the sensor
position.
PCBs are present on the
Work 1 and Work 2
conveyers when homing.
Take out the board or adjust the sensor
position.
PCBs are present on the
Work 2 and exit
conveyers when homing.
Take out the board or adjust the sensor
position.
Large offset between
the PCB width of the
conveyer and PCB
width in the Job file.
Check the conveyer width and the PCB
size. Check the job file.
The conveyer cannot
move because the Z-
axis is lowered.
Check the Z -axis position and then run
the conveyer.
ORG error during
conveyor operation
Carry out PCB Manual Control after Z -
axis homing.
Conveyor PCB
discharging error.
Check conveyer belt and sensor.
