3.4 Main distribution unit

Once the placement system has been switched on, the following voltages can be tapped at the

terminal strip for the main distribution unit (see block diagram "Main distribution unit, 00336154-

XXXXXXTD3 of the detailed circuit diagrams): 3

Stabilized voltages 3

5 VDC, ± 12 VDC, ± 15 VDC, 24 VDC 3

Non-stabilized voltages 3

10 VDC, 40 VDC, 52 VDC 3

3.5 Servo unit

When the main switch is switched on, the servo unit is supplied with the following voltages: 3

The test sockets are shown in the block diagram "HS-60 servo unit, front view, 00334810-

XXXXXXTD3, page 1" of the detailed circuit diagrams. 3

The ± 15 VDC supply voltages for the servo unit’s electronic circuits are generated from the ± 15 V

supply integrated in the servo unit and can be tapped at the measuring points of the power supply

unit (see HS-60 servo unit, front view, 00334810-XXXXXXTD3, page 2 of the detailed circuit dia-

grams). 3

Measuring point Measured against X1 - 0 V

X4 0 VDC for the servo amplifiers of the x/y axes

X3 4 VDC for the servo amplifiers of the star axis

X2 30 VDC for the servo amplifiers of the z and dp axes

3.6 Description of the power supply functions

The placement system cannot be used in placement mode until all the supply voltages have been

enabled by the protective circuit. The following conditions must also be fulfilled: 3

– All four component change-over tables must be docked.

– All covers must be closed.

– Both emergency stop push-buttons must be released.

– All four component flaps over the component tables must be closed.

– The software enable signal must have been sent.

The enable signal is then sent to contactor SZ4 in the power supply unit via port 2 (X2dm) of CAN

input/output module 1 in sector 4 of the distribution board (see block diagram "Distribution board,

sector 4, 00336153-XXXXXXTD3 in the detailed circuit diagrams). 3

Fig. 3.6 - 1 Power supply unit - partial front view

Contactor SZ4 switches 24 VDC to 3

– L+ on the combined contactor/protective device SSK

– the Start button at X4 of the SSK and

– the emergency stop loop at X3 and X5 on the SSK.

If 24 V is present at L+ on the SSK, the green "Power" LED on the SSK will light up. The message

"M ready" is returned to the computer via port 1 (X1dm) of the CAN input/output module 1 in sector

4 of the distribution board. If the safety loop is closed (covers closed, emergency stop button not

pressed), 24 V is sent to terminals X3 and X5 on the SSK. 3

If one of the Start buttons is pressed, the SSK switches and the green LEDs for channel 1 and

channel 2 light up. The five normally open contacts on the SSK switch five independent circuits

(see HS-60 power supply, 00336145-xxxxxxLD4, in the detailed circuit diagrams): 3

– Normally open contact 13-14 actuates SZ2, SZ3 and SZ 23.

SZ2 and SZ3 switch through the 200 VDC and 100 VDC link circuit voltages for the servo

amplifiers of the x, y and star axes. SZ23 switches the current limitation. 3

– Electronic load disconnecting relay ELR1 switches the 3 x 230 VAC operating voltage for

lifting tables 1 and 2 of conveyor 1,

– The optional relay ELR2 switches through the voltage for lifting tables 3 and 4 of conveyor 2.

– An auxiliary contact on contactor SZ23 sends a 24 V signal in the form of an "M_controller

ON" message to CAN input/output module 1 (X1dm) and in the form of a "ServoEnable"

message to the servo unit.

– Normally open contact 23-24 switches the 40 VDC operating voltage to the component ta-

bles.

– Normally open contact 33-34 switches through the 24 VDC operating voltage to the used

tape cutter.

– Normally open contacts 43-44 and 53-54 are provided for the safety loops of external mod-

ules.
