3. Function Details
This function measures the height of a head above the target tape guide, and calculates its
appropriate pick height. The result can be applied to board data. Therefore, you don’t need
any special equipment such as a laser measuring instrument to measure the pick height.
A head moves down to the feeder tape guide, and the height is calculated based on its
vacuum level. The result is translated to pick height and displayed on the screen.
It is possible to apply the measured pick height to board data, and to use it in production.
There are two types of tape guide, iron and carbon. They have different measurement
positions, so that it is necessary to recognize a tape guide by the moving camera. However,
if you use only either type of tape guide feeders, you can skip the guide recognition. To
recognize a guide, the special mark data is necessary. For more details, please refer to
Chapter 4 or 6.
Teaching head is supposed to pick the first one of the target feeder parts. If the first head
can’t measure the height, the second head does. If no head can measure the height, a
measurement error occurs.
In V4.50STD_R1.000 or later, it is possible to measure the height without mount data as
long as fixed board data is read. In this case, mounting heads and nozzles are automatically
determined. Please note that the determined combination of heads and nozzles will be
different from that you want to set.

Item Description
Measure
Pick height is measured for the parts selected on the grid.
Measure
Previous
Pick height is measured for the one before the selected parts on the grid.
Measure Next
Pick height is measured for the one next to the selected parts on the grid.
Auto Measure
When the [Measure Previous] or [Measure Next] button is pressed with
this button, pick height is measured for the next or previous parts in order
continuously.(Continuous teaching)
Feedback
When this button is pressed, teaching result is applied to pick height of the
selected parts.
All Feedback
All teaching results are applied to pick height of all parts.
Clear
Teaching result of selected parts is cleared.
All Clear
All teaching results are cleared.
< Caution >
- These items are grayed out when the feeder or nozzle of selected parts is unsupported.
At executing [Auto Measure], such feeders and nozzles are skipped.

- Teaching results are maintained until board data is read.
< Note >
- Pick height teaching is performed one by one.
- It takes about 5 to 6 seconds per point.
3.2 Pick Height Take Over Function
When [TakeOver PickHeight] is enabled in the machine setting, “Pick Height” is taken over
to other board data, so that you don’t need to perform pick height teaching for every board
data.
To take over pick height, the target parts need to be used for production, or the board data
is saved after pick height feedback. Target pick height is written and read through a
takeover file at reading board data, or when the feeder is removed and attached.

< Note >
・ File saving path is “D:¥Machine¥Status¥PartsTakeOver¥”, and can be changed on the
[Software Setting] – [Monitor] – [Parts Data Take Over] dialog.
・ When reading or writing of takeover file is failed, “Ea12994:
Failed to write parts data
take over file” or “Ea12995:
Failed to read parts data take over file” is recorded in the
error log.
