1.2 Conveyor speed
The conveyor speed varies according to the frequency of the power supply
and the weight of the PCBs on the conveyor. You can adjust the carry-in
and carry-out conveyor speeds by using the adjustment screws located
inside the lower right panel on the front side.
The YV180X conveyor section is divided into 4 conveyors: carry-in
conveyor, B-table conveyor, A-table conveyor and carry-out conveyor. The
carry-in and carry-out conveyors each move at two different speeds: a high
speed (H) for reducing the transfer time of PCBs and a low speed (L) for
minimizing impact when the PCB hits the entrance stopper and exit
stopper. To adjust these speeds, prepare typical PCBs and use the proce-
dure below.

1 Adjust the conveyor width according to the size of the
PCB.
To adjust the conveyor width, the <3/4A0 CONVEYOR UNITS> - ”CONV.
WIDTH” command will prove convenient.
2 Open the output monitor screen and turn on the conveyor.
1. Select <3/4/A1 INPUT/OUTPUT MONITOR> - “SELECTION” -
“CONVEYOR” and press the [ENTER] key.
2. Use the arrow keys to line up the cursor with “T1834” (ENT. CON-
VEYOR ON).
3. Press the [ENTER] key to turn on the conveyor.
The output monitor digit for “T1834" reads “1” when the conveyor is
on and reads “0” when it is off.

3 While running the conveyor, switch the speed.
1. Use the arrow keys to line up the cursor with “T1835” (ENT. CON-
VEYOR SPEED CHANGE) .
2. Press the [ENTER] key and check the conveyor speed.
The output monitor digit for “T1835" reads “1” when the conveyor is at
low speed, and reads “0” when at high speed.

4 Adjust the high speed.
While running the carry-in conveyor at high speed, adjust the speed by
turning the “H” screw.
Do not set the speed too high, as this may hamper switching response.
Position the “H” screw at a point slightly slower than the maximum speed.

5 Raise the entrance stopper.
1. On the OUTPUT MONITOR screen, move the cursor to “T1925” (ENT.
CONVEYOR STOPPER).
2. Press the [ENTER] key to raise the entrance stopper.
The output monitor digit for “T1925” reads “1” when the entrance
stopper is raised, and reads “0” when it is lowered.
6 Adjust the low speed.
While running the carry-in conveyor at low speed and carrying in a PCB,
adjust the speed by turning the “L” screw. Adjust the “L” screw so that the
PCBs are not subjected to a strong impact when they hit the entrance
stopper.
7 Adjust the carry-out conveyor speeds in the same way.
The output monitor codes used to adjust the carry-out conveyor speeds are
as follows.
“T1826” (EXIT CONVEYOR ON)
“T1827” (EXIT CONVEYOR SPEED CHANGE)
“T1926” (EXIT CONVEYOR STOPPER)
8 Quit the adjustment.
After pressing the emergency stop button, remove the PCB from the
conveyor. (There is no machine data to be saved in this adjustment.)
