The “Production lane information” tab allows you to display/hide the production lane information on
the upper section of the “Production status (Vision)/(Operation condition)/(Number of produced
PWBs)” screen.

2.14 Process of PWB Production
Conditions necessary to operate the ZA-axis at a 3mm-height
The following shows the conditions necessary to operate the ZA-axis at a 3mm-height. To operate
the ZA-axis at a 3mm-height, all of the following conditions need to be satisfied.
No. Conditions
1 "Head height at production start" of the Machine Setup is 1 mm or less.
2 The maximum value of "component height + pickup depth" of a component to
be placed by this machine is 1 mm or less.
3 The maximum diagonal length of a component to be placed by this machine is
less than 86 mm.
4 The maximum pickup height is 1 mm or less.
5 The maximum component height + PWB height (only when the PWB height is
positive) of a component to be placed by this machine is 1 mm or less.
6 The component height - placing stroke (only when the placing stroke is
negative) is 1 mm or less.
7 The height of the placement PWB surface is not measured.
8 The height of the head at the production start of the production program is 1 mm
or less.
9 No RF/EF bank, MTC, and MTS are mounted.
10 Only the RF type feeder is mounted on the RF bank.
* Whether the ZA-axis can operate at a 3mm-height is judged on the front and rear.
When the front supply is possible at a 3mm-height and the rear supply is impossible at a
3mm-height, the ZA-axis operates at a 3mm-height only during front supply.
◆ The operation at the ZA-axis height may vary depending on the number of transport buffers.
1) When the option “ZA-axis operation with the substrate size for 3 buffers” is disabled in
3-buffer mode, the height of the ZA-axis is adjusted to the highest one of all component
placement positions.
2) When the option “ZA-axis operation with the substrate size for 3 buffers” is enabled in
3-buffer mode*, the ZA-axis is adjusted to the highest one of the positions at which
components have been already placed.
3) In 1-buffer mode, the ZA-axis height is adjusted to the highest one of the positions at which
components have been already placed.
* Since the ZA-axis operates differently depending on the board size, see Section 12.6.4
“ZA-axis operation with the substrate size for 3 buffers” for details.
CAUTION
If any value shown above is set incorrectly, the head may interfere with other unit.
Be sure to enter the correct set values.

Resuming return of all axes to their home positions
When you press the <START> switch if the system can return the axes to their home positions
respectively to resume PWB production, the screen for returning them to the home positions
including the <Servo lock> button appears.
To display the screen for returning the axes to the home positions to resume PWB production, all
axes have returned to their home positions at least once.
The requirements for returning the axes to the home positions to resume PWB production
after an asynchronous event that turns off the servo power supply occurs are shown below.
No. Asynchronous event
Resuming returns of all axes
to the home positions
1 The main unit is in Emergency Stop mode. O
2 The feeder floats, and the system stops temporarily. O
3 The limit sensor of each axis is activated. O
4 The alarm is raised at each axis. O
5 The area sensor is activated. O
6 POWER OFF (CE machine) O
◆ If either of the following events occurs, the system cannot resume returning all axes to their
home positions:
① All axes have not been returned to their home positions at least once.
② Although the system already tried to resume returning all axes to their home positions, it
failed.
