5. The Servo System
The servo system is responsible for the motions of the machine. This system carries the board(s) to
the correct placing position, carries the tape feeders to the component pick-up point, rotates the cam
turret, changes nozzle sizes, and also accurately rotates components to the desired placing angle.
The following section details the individual components of the loading position and the step-by-step
procedure for adjustments vital to maintaining this system.

5.1 Servo System Components
A simplified illustration of the CP-6 series servo system is shown below.
CP6M5075
The servo system for the FCP-6 is a semi closed-loop system. The system consists of the
CPU and Servo boards, servo amplifiers, servo motors and servo motor encoders. The
semi closed loop configuration is achieved through the encoder-to-amplifier connection.
The machine uses the constant stream of positional data from the encoder to alter the
position of the motor. This allows the machine to keep a very tight placement tolerance
and a high rate of repeatability.
HMIV-134 CPU Board
The CPU board controls all functional decisions undertaken at the machine. This card is
responsible for the initiation of all servo axis motions.
IS70B Servo Boards
There are three servo driver cards in the VME card rack and these cards interface the
CPU board to the servo amplifiers. The first card controls the CAM, FRQ- and Z-axis.
The second card controls the X-, Y- and FQ-axis. The third card controls the D1-, D2- and
NC-axis. The cards take the binary movement data (in pulses) and direction commands
from the CPU board and send analog signals to the servo amplifiers which in turn drive
the motors.
