PLC ERRORS

3000 ‘ (PLC_ERR without description) ‘

DETECTION

EFFECT

CAUSE

SOLUTION

During execution.

It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of all channels.

Marks ERR1 to ERR64 have been set to "1".

Check at the PLC why these marks are set to "1" and act accordingly.

3001 ‘WATCHDOG in the main module (PRG).’

DETECTION

EFFECT

CAUSE

SOLUTION

Any time.

It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of all channels.

Besides this, it activates the external emergency output.

The possible causes are:

1. The execution of the PLC’s main program has exceeded the time set in PLC parameter WAGPRG(P0).

2. The program is in an endless loop.

Increase the time of PLC parameter WAGPRG(P0) or increase the PLC speed.

• Insert CPU TURBO.

• Change PLC parameter CPUTIME(P26) or general parameter LOOPTIME(P72).

3002 ‘WATCHDOG in the periodic module (PE).’

DETECTION

EFFECT

CAUSE

SOLUTION

Any time.

It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of all channels.

Besides this, it activates the external emergency output.

The possible causes are:

1. The execution of the PLC’s periodic program has exceeded the time set in PLC parameter WAGPER(P1).

2. The program is in an endless loop.

Increase the time of PLC parameter WAGPER(P1) or increase the PLC speed.

• Insert CPU TURBO.

• Change PLC parameter CPUTIME(P26) or general parameter LOOPTIME(P72).

3003 ‘Division by zero at the PLC’

DETECTION

EFFECT

CAUSE

SOLUTION

Any time.

It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of all channels.

Besides this, it activates the external emergency output.

In the PLC program, there is a line whose execution implies a division by zero.

When working with registers, that register may have already acquired a zero value.

Check that the register does not reach the operation with that value.

3004 ‘PLC error ->’

DETECTION

EFFECT

CAUSE

SOLUTION

Any time.

It stops the movement of the axes and the spindle, eliminating all the enable signals and canceling all the analog outputs of the CNC. When detected from the position loop, it opens the position loop and sets the LOPEN mark to ·1·.

If it is in execution, it interrupts the execution of the part program of the CNC of all channels.

Besides this, it activates the external emergency output.

An error has been detected on the PLC board.

Replace the PLC board. Contact the Service Department.

3005 'Contacts debugging error'

DETECTION

CAUSE

SOLUTION

While debugging the PLC program.

When debugging the PLC program to create the PLC program in contacts (ladder), the CNC finds an error in that program.

Check if it has been properly compiled.

3006 'The PLC program does not exist'

No explanation required.

3007 'Configuration file corrupted'

DETECTION

CAUSE

SOLUTION

At any time, while being on the <CONTACTS> screen.

An error has occurred in the configuration file.

Exit the <CONTACTS> screen and go back into it.

3008 ‘PLC program too large’

DETECTION

CAUSE

At any time, while being on the <CONTACTS> screen.

The PLC program has exceeded the maximum size limit.
