1.1 Major Components

The machine’s I/O system is comprised of the CPU card, 3 servo cards, the VME

interface card, 2 PLC’s, 3 servo I/O interface cards and the various relays, sensors and

motors of the machine.

CPU Card HMV 134

All machine functional decisions are made here. The CPU uses the various input signals

to control/confirm desired functions, while using the output signals to initiate these

functions. Many of the alarms that appear on the machine monitor can be traced back

through the I/O.

Servo Cards IS70B

These cards interface the CPU card to the servo amplifiers, but “Connector 4” on each of

the cards monitors the zero set sensors and overtravel sensors for the servo axes

controlled by that card.

VME Interface Card MX250V01

This board interfaces the VME bus (mainly the CPU card) to the Programmable Logic

Controllers (PLC’s). For an output, the decision is made by the CPU to turn on/off a

port (relay, solenoid, LED, etc.) and the signal travels to this card via the VME bus. The

card then routes the signal to the proper PLC (either the direct I/O or the loader I/O

PLC). The actual switching signal is sent by the PLC (usually to a relay), which actually

drives the device (solenoid, valve, etc.). The input side works the same way but in an

opposite path.

Programmable Logic Controllers (PLC) MX100 / MX 250

FUJI has steered toward the mainstream and away from direct VME I/O controls. The

VM-1540 has been eliminated from new FUJI SMT machines. In its place, PLC’s now

perform the function of I/O management. There are two PLC’s in the CP-6. The larger

of the two is called the “Direct I/O PLC”. It handles all main machine inputs and

outputs. The second PLC is called the “LOADER PLC”. It controls only loader functions

(i.e. anything related to the conveyer).

This PLC consists of four portions: CPU, Input module, Output Module and the Relay

Module. The CPU module controls the other three. It is driven by logic found on a

control ROM located under the blue access panel. Modules of the same type are

interchangeable and may be swapped.

1.2 The I/O Menu

Accessing the I/O

There are three ways to access the status of the I/O on the CP-6 series machines:

a. Through the machine menus

Each input and output has its own separate name and address which may be seen by

pressing [SET], [MANUAL] and [I/O].

b. Direct I/O Entry

The alternate method of entering the I/O, called direct I/O entry, may also be initiated

by:

1. Turning the machine OFF.

2. Hold the black F1 key down.

3. Press the POWER ON key.

4. Keep the F1 key held down until the first color (I/O) menu comes up.

c. Visual Observation of the PLC LEDs.

This procedure puts the operator directly into the I/O. The main purpose of this mode is

for troubleshooting. The machine should be turned off after troubleshooting is

completed.

1.3 Using the I/O Map

Using the I/O map is quite simple. Once in the I/O menu, the operator has a choice to

choose the Input side to work with, or the Output side. Only one side may be accessed

at a time (although both are displayed on the screen at the same time). When a side is

selected, the [PAGE +] and [PAGE -] keys become active. Locate the desired port with

these keys. The UP and DOWN arrow keys may also be used to move the cursor one

port location at a time.

The Input side only reports the current input state of the port. If the the input terminal is

connected to DC ground, then a green ‘0’ (active) will appear in the I/O MAP for that

port address. Otherwise, a yellow ‘X’ (not active) will appear for that port. If the cursor

is on the port and the port is active, then the buzzer will be turned ON.

The Output side allows the operator to change the state of the port with the ON/OFF

key. Pressing this key will toggle the current state of the output port. A yellow ‘X’

means ‘not active’ and a green ‘0’ means ‘active.’
