Description of CAN node NC tape cutter module
The introduction of the SIPLACE X4I and the further development of the SIPLACE X series also brings
with it the integration of the nozzle changer control and the monitoring sensors into the machine CAN
bus.
This new board is named "CAN node NC tape cutter module" [03052927-xx] and is used in place of the
former tape cutter board.
This board contains the control system for the tape cutter unit, NC 1 and 2, nozzle station (blast air valve
for C&P20A head) and sensors for the component/nozzles reject bin.
The firmware for the CAN nodes is loaded onto the tape cutter board with the help of the station software
or CACCIA.
The "CAN node NC tape cutter" is backwards compatible with the old tape cutter boards. This assembly
can therefore be used in X, HF and D series machines.

Based on the cables connected and the position of the DIP switch, the CAN processor detects which
functions are to be controlled and at which location each assembly is.

The power connection has 2 pins for selection of the suitable CAN ID. This depends on the position
(location) of the CAN node module in the machine.

Principle circuit for position measuring systems
Legend
The axis control system with closed position control circuit determines the axis position directly, based
on the mechanical movement of the axis. The position measurement system generates analog track and
zero pulse signals during movement over the incremental scale. An amplifier, a frequency multiplier
circuit and a signal former are integrated into the amplifier housing. A test connector for digital signals is
either installed on the next interface board or the digital signals are measured at track A/B and the zero
pulse output of the SIPLACE AxisTester. The track signals are the only feedback loops in all the axis
control systems of the SIPLACE machine. This means that each track recognition error affects the axis
control system. The gantry axes immediately stop at a fault; the head axes finish the positioning to target
before showing a track signal error.
NOTICE
The old nozzle changer of the C&P20 head can not be used together with the CAN node NC
tape cutter module.
The nozzle changer with new control board can also be used in machines without the CAN
nodes.
