The main reason for the transformer T1 is to power the X/Y and star axis, protected by F4. Contactors
K2, K3 and K4 illustrate fixed elements of the electrical safety concept. In a fault event, e.g. open cover,
the servos are disconnected from the energy.
Primary Transformer T1
▪ 250 VDC for the servo amplifiers of the x and y axes.
▪ 150 VDC servo amplifiers of the star axis.
▪ 34 VDC for the inrush current limiter servo
▪ 52 VDC for the DC/DC converters in the main power unit
▪ 48 VDC for DC/DC converter of camera illumination and the computer unit

Overview of main voltage supply and transformer
Transform er T2
5.2.4.4 Transformer T2
The main task assumed by transformer T2 is to power the Z and DP servos, protected by F6.
Secondary transformer T2
▪ 40 VDC for the servo amplifiers the z and dp axes.
▪ 34 VDC for PCB handling system.
▪ 40 VDC for the component tables (30 V for feeder operation).
▪ 10 VDC for the component tables (5 V for logic).
▪ 28 VDC for the monitor.
▪ 24 VDC for cooling the Y axis motor. (motor generating compressed air)
