5.2.10 Various Signals
5.2.10.1 Software Release (Software Enabled)
The software release signal is given by the CAN I/O card when the machine controller software is fully
booted. This means that not only must the machine controller software be booted but communication
must be established to the Vision system, axis boards, CAN BUS, station computer and line computer
(unless it is operating in stand-alone mode). When the start button is pressed, the CAN I/O module
issues the 24V output signal and 24V is present K5, contact A1.
If the emergency STOP circuit is interrupted, the software release will not be issued.

5.2.10.2 OK Signal Safety Loop
The message
Safety loop OK
will be emitted by the CAN I/O module, if the following conditions have
been fulfilled:
All covers closed
All component tables connected
All emergency STOP buttons released
Emergency STOP circuit closed
The 24 V output from the CAN I/O module is present at the main voltage supply (inrush current limitation
board) and GND is switched through to contact 6.

1. BTS 117: voltage switch for GND
This signal is transmitted to the power supply X8-20 and connects GND to SSK, contact X6.

5.2.10.3 Control On Signal
If connector K4 of the power supply is enabled, the auxiliary contact K4.5 will close and 24 V (servo
release signal) will be present from the DC/DC converter to the distributor of the main power supply X13,
to the axis unit X21 and to the anti-crash board.
The introduction of the A364 also involved direct software realization of the anti-crash function on the
axis card.
Here it is split in 2 paths:
Path 1: 24 V present as
Servo enable signal
at the X/Y axis servo board, to enable the servo amplifier
(to switch GND to the servo board via optical coupler).
Path 2: 24 V present as
Ctrl_ON
signal at sector 2, connector X4qa and ends as M_Ctrl_On at the CAN
I/O module. The 4 main axis is allowed to move now into any position.

5.2.11 Power Distribution
The power distribution to the different sectors, gantries and heads is highly structured. 5V and 24 V,
generated by DC/DC converter U20 and U30 in main power supply, will first activate at distributor main
power supply, connector X16. Then at section 2, main distributor, connector X2qa and then at the
terminal block X1qa for general use, at connector X71qa and at last at connector X71ra, section 4.
52 V for camera illumination, generated by U7, is activated at main power supply distributor, X18, and
split into two paths.
Path 1: from X18, at section 2, X3qa, to terminal strip X1qa and then to the DC/DC converter Vision for
converting the 42 V needed for the IC/FC camera illumination. The voltage is also present via connector
X71qa to connector X71ra in sector 4 and to X1ra, ending at the DC/DC distributor Vision (42V are not
used here).
Path 2: (this path is currently not used) from X18 at sector 2, X3ra, to terminal strip X1ra and then to the
DC/DC distributor Vision for converting the 42 V needed for IC/FC camera illumination in this sector.
The voltage supply +/-15 V is generated at the power pack in the axis unit from the 52 V and is then
present at X4qa, at the terminal strip X1qa, for general distribution and use. The voltage is then present
via X74qa to X74ra in sector 4 to the intermediate distributor (not shown in the following diagram).
