3.9 X feeder modules for SIPLACE SX1/SX2
The SIPLACE SX1/SX2 uses the entire spectrum of the SIPLACE X feeder modules. All SIPLACE
X feeder modules are compatible with the changeover tables of the SIPLACE SX1/SX2 and can
be used without restrictions. Key properties of the SIPLACE X feeder modules include the high
precision of the pickup position, online programmability, status displays on an LCD display and
simple handling for feeder module changes during the placement process. The power supply to
the feeder modules is contactless and uses an inductive interface. Each feeder module commu-
nicates with the feeder module control unit (FCU) via two optoelectronic channels (optical fiber).
The two interfaces form the EDIF assembly (energy and data interface, see item 2 in fig. 3.9 - 1
,
page 146
). The feeder module control unit is connected to the control unit of the machine via the
CAN bus.
3.9.1 Tape feeder modules for the SIPLACE X-Series
3.9.1.1 Tape material
The possible tape widths range from 4 mm to 88 mm. The tape material is blister or paper. Com-
ponent tapes with a permanently adhesive cover foil (PSA foil) can also be processed. This will
require the "PSA Kit" option.
The design of the tape feeder modules was based on the following tape standards:
DIN EN 60286-3 (12/1998) / IEC 60286-3 (12/1997)
JIS C 0806-3 (1999)
ANSI/EIA 481-C (10/2003)
IEC 60286-3-2 3
PSA Kit Item no.
