MALFUNCTION PREVENT FUNCTIONS

Overview

These functions monitor the CNC internal status and check that related data is within the allowable range.
If an invalid state due to a deteriorated hardware component or noise is detected, these functions stop the
machine with an alarm to prevent any malfunction.

Explanation

Each function is detailed below.

Checking the maximum speed of the servo motor

This function checks whether the maximum speed specified in parameter No. 12255 is exceeded. If the
maximum speed is exceeded, this function issues alarms DS0004 and PW0006 and stops the machine.
When the parameter is set to 0, this function checks whether the maximum speed (999000 for IS-B) is
exceeded.

Checking the maximum acceleration of the servo motor

This function checks whether the maximum acceleration specified in parameter No. 12256 is exceeded. If
the maximum acceleration is exceeded, this function issues alarms DS0005 and PW0006 and stops the
machine. When the parameter is set to 0, this function does not check the maximum acceleration.

Checking the maximum speed of the spindle motor

This function checks whether the maximum speed of the spindle motor is exceeded. If the maximum
speed is exceeded, this function issues alarms IE0007 and PW0006 and outputs S0. The parameter which
specifies the maximum speed of each spindle is used.

Checking the stored stroke limit at the end point

This function makes a stored stroke check immediately before pulses are output in addition to a normal
stored stroke check. If the stored stroke limit is exceeded, this function issues one of alarms IE0001 to

2. PREPARATIONS FOR OPERATION

B-64693EN-1/01

- 588 -

IE0006 and alarm PW0006 and stops the machine. The parameters for normal stored stroke checks are
used.

Monitoring execution of NC command analysis

This function monitors NC command analysis to check the execution counter and reference area for
validity. If invalid data is detected, this function issues one of alarms DS0006 to DS0013 and alarm
PW0006 and stops the machine.

Monitoring execution of acceleration/deceleration after interpolation

This function monitors the execution counter during execution of linear/bell-shaped
acceleration/deceleration after interpolation to check the counter for validity. If invalid data is detected,
this function issues alarms IE0008 and PW0006 and stops the machine.

is exceeded, the servo motor stops with the alarm DS0004. When 0 is set in this
parameter, the specification of a maximum allowable value (999000 for IS-B) is assumed.

This parameter sets a maximum servo motor acceleration rate. When the value set in this
parameter is exceeded, the servo motor stops with the alarm DS0005. When 0 is set in
this parameter, alarm check is not performed.

Alarm and message

The machine is decelerated and stopped when a DS alarm is issued or is immediately stopped when an IE
alarm is issued to prevent any malfunction.
Check the block in which the machine is stopped. If you cannot find the cause, contact FANUC without
releasing the alarm state.

OPERATOR ERROR PREVENT FUNCTIONS

Overview

If an invalid value is set for tool offset or the machine is operated improperly, a workpiece may be cut
incorrectly or a tool may be damaged. If data is lost due to an operator error, time is required for recovery.
The operator error prevent functions include the following functions to prevent an unintentional operator
operation (called an operator error below).
1.

Functions operating during data setting
-

Checking whether offset data is within the valid setting range

Reconfirming incremental input operation

Disabling absolute input using soft keys to prevent an operator error related to absolute and
incremental input

Reconfirming deletion of a program or all data

Reconfirming data update during setting

Functions operating during execution
-

Highlighting updated modal data

Displaying the status of the execution block before execution of a program

Displaying the axis status such as the mirror image enable state or interlock enable state

Checking the start of a program from a midpoint

Checking whether offset data is within the valid setting range

Checking the maximum incremental amount

2. PREPARATIONS FOR OPERATION

- 590 -

Explanation

Functions operating during data setting

The following functions are provided to prevent an operation error during data setting.
-

Checking of the input data range

Reconfirming of incremental input

Prohibiting of soft key absolute input

Reconfirming of program deletion

Reconfirming of all data deletion

Reconfirming of data update during setting

For details on these functions, refer to the OPERATOR’S MANUAL.

Functions related to checking before execution

The following functions are provided to prevent an operation error during execution.
-

Update display of modal information

Start check signal

Status display of axes

Reconfirming of midway block start

Checking of the execution data range

Checking of the maximum incremental amount

For details of functions other than the start check signal and bit 0 of diagnosis information No. 3570, refer
to the OPERATOR’S MANUAL.

Start check signal

If cycle start is performed when the start check signal STCHK <Gn408.0> is 1, the stop state is entered
with the remaining traverse distance and modal of the execution block indicated. Performing cycle start
again starts the execution.
An operation error is prevented because the status of the execution block can be checked before
execution.
Using the start check signal together with the update display of modal information shown above makes
checking easier.

During a memory operation stop

If memory operation is stopped due to the reconfirming of midway block start, bit 0 of diagnosis
information No. 3570 is set to 1, so that the state can be confirmed.
In a multi-path system, bit 0 of diagnosis information No. 3570 is set to 1 on only the path on the cursor is
position in the middle of the program.

Signal

Start check signal STCHK<Gn408.0>

[Classification] Input signal

[Function] The traverse distance and modal can be checked before execution.

[Operation] When this signal is “1”, the remaining traverse distance and modal is displayed before

executing a block and then execution stops. Performing cycle start again starts the
execution.

Middle block start signal MBSO<Fn534.4>

[Classification] Output signal

[Function] Indicates that memory operation is stopped by the reconfirming of middle block start of

the operator error prevent function.

[Output cond.] The signal is set to “1” when:

Memory operation is stopped by the reconfirming of middle block start of Operator
error prevent function.
