R (real time) command is to inform the host computer of the changes of conditions during the production

work of AVK3 whenever they occur. This is used as a remote control or to collect production control

information. However, when the host computer is used just for transmission of NC data, if R command is

received, it causes inconveniences. As indicated in ‘1.1.6 Changing Data Transmission Mode’, it is possible

to use the selector switch so that R command does not occur.

6.2.1 Production Quantity Information: R0

R0 Command is used for totaling the hours worked by AVK3 which started operating by the remote control

command. R0 command has the following 4 functions.

 Data details

1. CT

This occurs only when stop mode is in “CONT” and NC program has executed the EOP block.

In case of error, this signal occurs only when restarted in “CONT” mode.

Usually, this is used for counting PCB production.

2. EP

This occurs only when stop mode is in “EOP” or “1BLOCK” and NC program has executed an EOP

block.

Therefore, when an error has occurred at the final dispense block, this signal will not be generated until

operation is by “EOP” or “1BLOCK” key.

This signal can be used to end production. In this case, R0CT is not output.

3. BDGD

In the bad mark sensing corresponding machine, this verifies with the bad mark sensor if the PCB is

capable of being inserted before the actual insertion action.

If it is found to be capable of being inserted, this signal is generated.

4. BDNG

In the bad mark sensing corresponding machine, if the verification results find the PCB as being

incapable (inhibit) of being inserted, this signal is generated.

6.2.2 Operation mode information: R1

The R1 command is to let the host computer know when an operator or host computer is positively operating

the control switches on the AVK3.

 Data details

1. OL or FL

These commands inform the host computer that the control mode of AVK3 is the online (OL) or off-line

(FL). This is generated when mode select switch on the main control panel of AVK3 is switched over,

or immediately after the power is turned ON.

2. ES

When the power is shut down by an emergency stop, R1ES command is outputted by the contact input

of ES switch.

3. ST

This command informs the host computer that AVK3 has started because the START switch on the

main control panel was pressed or a C5ST command was input from the host computer. This is the

signal output when AVK3 has started operation. This signal is also output at the time of restart.

4. SP

This command shows that AVK3 has stopped in conditions other than error.

Actually, it is the normal stopping of 1. Block operation other than at the final print block.

When the NC program switch is “EOP”, this command is not sent and R0EP command is output to

distinguish from stop in EOP stop mode.

5. PS

When a PCB is transferred to the start of the loader rail, the PCB detector 2LS goes ON. When this

switch goes ON (when the PCB is correctly set on the loader rail), this command is output. When

inputting a C5ST start to the AVK3, It is necessary to check that this R1PS command has been

previously input to the host computer.

6. RE

When the “OPERATION RESET” switch on the main control panel has been pressed by the operator

or the C5RE command has been executed by the host computer.

7. PW

In the NC program when G1T4 command is executed, X-Y-Z axes return to origin point and PCB

loading is conducted on X-Y table. At this time, if there is no PCB at the head of the loader rail (that is,

if R1PS command has not occurred prior to it), it is in the PCB arrival waiting condition. In such

conditions, this command occurs.

This signal also occurs when it is impossible to convey away the PCB on the loader rail because the

unloader stocker is full, and PCB loading is impossible.

8. PE

This command shows that the above-mentioned R1PW command condition has been eliminated.

That is, after R1PW has occurred, this command occurs when PCB arrived at head of loader rail, or

when PCB has been discharged to unloader.

9. OC

This is the command informing the host computer that the XY axes started origin return action and

completed the action through inputting C5UP command (PCB sweep out command) from the host

computer.

10. UP

Sweeps out PCB in XY tables through inputting C5UP command from host computer. This is the

command informing the host computer of the C5UP action completion when PCB sweep out was

completed.
