5.1.5.2 MHCU General
The task of the MHCU is the position control of the head axis (C&P20 P, CPP und Twin Head).
Further the MHCU integrates the functions of the PRV, the component sensor and the
communication interface for the DP Axis.
The unit consists of a control module (CM) and a power module (PM) comparable to the axis card
as control module and the servo card as power module.

MHCU Function Power Supply
The power supply delivers 42V for the electronic and Z Axis.
The power cube on the head interface (C700) supplies the MHCU with 25V.
All required internal voltages (+24V, +15V, -15V, +5V, +3.3V, +1.5V) are generated by the head
interface at the gantry.
In addition, the operating voltages for the axes (150 V for Star / 42V for Z) are supplied by the
machine power supply.
MHCU Function
The head control unit is responsible for central control and adjustment of the axis and also for
communication with the station computer via CAN bus.
Tasks of the software application:
●
BIOS is responsible for the booting of the MHCU
●
Application 1: communication with machine software
●
Application 2: motor control
