4.2.6 Power Supply Axis Unit
When the main switch is on, the axis unit is supplied with 52 V from main power supply via X13
and generates the voltages as shown below.
The +-15V and 5V supply voltages for the servo unit’s electronic circuits are generated from the
two DC/DC converter, which are integrated in the servo unit. This DC/DC converter generates the
5V and +- 15V needed for the servo board and the axis controller and the +-15V are also used on
placement heads and anti-crash, for e.g. It will travel to main distributor X4qa (sector 2) and then
to terminal block X1qa and get distributed from here.

4.2.7 DC/DC Converter Vision section 2
This DC/DC converter is only used for generating 42 V for P&P camera illumination as well as the
power distribution for PCB camera (5/24V) and component camera (24V).

4.2.8 Safety and Control Loop(HF/HF3 bis MA.Nr. xx)
Please Note: For machine type A you consult the enclosed circuit diagrams.
4.2.8.1 Émergency Stop Loop (safety loop)
Following contacts are switched in serial and build the safety loop: _ 4
– 4 protective cover switches (main cover).
– conveyor cover switch.
– contact on component change over table
– emergency stop button must be released
Fig. 4.2 - 13 safety loop
If the emergency stop loop is closed, 24 V will be present on K5, contact 3. Another 24 V signal
travels to each CAN I/O module as
’emergency stop loop OK’ and signalize that all covers are
closed and table connected.
