each feeder type.
[2] For the 8mm large reel, it is possible to have the feeder occupy only one slot if its
outermost width is less than 13mm.
[3] The actual part feed pitch of feeders larger than 12mm may be limited by the length in
the part supply direction and reel pocket depth. For further details regarding this, contact
our CS company (STS) and local agent after checking the corresponding dimension
information.

Overview
1.3. Reference for feeder’s pickup height setup
The reference plane for Z-axis height of the tape feeder is beneath (above the main frame)
the tape at the pickup position.
Actual pickup height of each part may vary depending on part height and transfer tape
thickness as shown in the following figure. In particular, embossed tape must be set
according to the actual part height against the pocket depth. It may become a negative (-)
value as shown in the following figure.

The Z value of the pickup point is applied in various ways according to the feeder type. In
addition, the Z value of the pickup point also varies according to the type of the part
supply tape. The embossed tape must be set according to the pocket depth and part height.
Sometimes, the pickup Z value is indicated as a negative (-) value.
