Caution

To save CNC information for eight or more days, so number of saving information each day is restricted.
The history can be saved only up to the potential saving number. (Refer to “Restriction of saving”)
So, in the ladder program, please judge trouble as accurately as possible.

Do not save CNC information at the time when trouble does not occur in order to decrease the load of
CNC.

At shipment of CNC, Potential Saving Number is 30.

CNC information might not be able to be saved correctly immediately before the power failure. So in the
system that can detect power failure, don’t save the CNC information when the power failure occurs.

SERVO/SPINDLE WAVEFORM DATA OUTPUT FUNCTION

19.2.1

Outline

When something trouble occurs with machine, servos and spindles waveform data before and after the
trouble is automatically output to Data Server, which is sampled by Trouble diagnosis function.
Since long-termed data is automatically saved, it is easier to detect the cause of the trouble.

CNC always samples waveform data.
If something trouble occurs with machine, CNC detects the trouble through alarms or signals and output
waveform data before and after the trouble to Data Server automatically (Fig.19.2.1(a)).

Fig. 19.2.1 (a) Outline of Servo / spindle waveform data output function

NOTE

This function requires Data Server function.

19.2.2

Waveform Data

This function can output several kinds of data listed in tables below.
Each data can be sampled for up to 40 seconds summing up before and after trouble.

Whole data of all axes can be output, though output data can be selected by parameters.

NOTE

The upper limit of sampling time cannot be extended even if output data is
reduced.

19.2.3

Sampling

It is necessary to always sample waveform data in order to use this function.
Trouble diagnosis data monitoring signal TDDM<G0589.0> starts the sampling.
Trouble diagnosis data monitoring signal clears latched data of Trouble diagnosis function and changes
the state of the function from “LATCHED” to “SAMPLING”.

Output of waveform data to Data Server starts when sampling after trouble finishes, which is specified by
parameter No.24320.
It is necessary to start sampling again by trouble diagnosis data monitoring signal after outputting of
waveform data.
Weather the output finishes or not is indicated by Waveform data transfer signal WVTRNS<F0578.0>.

Restriction

When this function is effective, the state of Trouble diagnosis function, “SAMPLING” or “LATCHED”,
is common for all paths, though the state can be different for each path in ordinary Trouble diagnosis
function. Therefore, Trouble diagnosis data monitoring signal starts sampling of all paths simultaneously
and trouble in some path stops sampling of all paths.

B-64693EN-1/01

19. MAINTENANCE FUNCTION

- 2839 -

NOTE

1 Latched data of Trouble diagnosis function and waveform data sampled by this

function is cleared when sampling restarts after trouble.

2 Though Trouble diagnosis data monitoring signal is for each path, this function

uses only the signal of 1st path.

3 Trouble diagnosis data monitoring signal is ignored when SV or SP alarm occurs

in some path. Start sampling by Trouble diagnosis data monitoring signal after
confirming that no SV or SP alarm occurs in all paths.

4 The state of sampling (the state of Trouble diagnosis function) does not change

even if power is turned off and on. Therefore, it is necessary to start sampling
after power is turned on if sampling was stopped (the state of Trouble diagnosis
function was “LATCHED”) before power was turned off. Oppositely, sampling is
started automatically after power is turned on if sampling was active (the state of
Trouble diagnosis function was “SAMPLING”) before power was turned off.

19.2.4

Detect Trouble

SV or SP alarm changes the state of Trouble diagnosis function into “LATCHED” when the state is
“SAMPLING”. At the same time, CNC regards that something trouble occurs with machine and the
sequence of outputting waveform data of servos and spindles to Data Server is started.

This function makes it possible to detect trouble by changing Trouble diagnosis data latching signal
TDDL<G0589.1> from “0” to “1” as well as SV and SP alarms. Weather trouble is detected by Trouble
diagnosis data latching signal or not is specified by bit 1 (SPT) of parameter No.24318.

NOTE

1 Though Trouble diagnosis data latching signal is for each path, this function uses

the signal of 1st path.

2 Data of Trouble diagnosis function is latched and the state changes from

“SAMPLING” to “LATCHED” when trouble is detected by Trouble diagnosis data
latching signal.

3 Sampling continues for a while after trouble is detected, which can be specified

by parameter No.24320.

4 Trouble is not detected and this function is not active when the state of Trouble

diagnosis function is “LATCHED”.

19.2.5

Sequence when Trouble Occurs

Servos and spindles waveform data is sampled with constant period and, if trouble occurs, data before and

after the trouble specified by parameter Nos.24319 and 24320 is output to Data Server. The output is
started automatically if sampling after the trouble finishes, which is specified by parameter No.24320.

Waveform data transfer signal WVTRNS<F0578.0> is “1” between the occurrence of the trouble and the
end of the output.
Sequence when trouble occurs is shown in Fig. 19.2.5 (a) and Fig. 19.2.5 (b) below.

NOTE

1 Make it impossible to turn off power during Waveform data transfer signal is “1”

in order to output data normally.

2 Sampling cannot be started when Waveform data transfer signal is “1” or SV/SP

alarm occurs. In addition, Trouble diagnosis function and this function are not
effective in such cases.

19.2.6

Data Output

Output of waveform data to Data Server is started automatically if trouble is detected and sampling after
the trouble finishes, which is specified by parameter No.24320.
“OUTPUT” is blinking at Status bar during the output.
The data is output to “SVSPWAVE” folder below Data Folder on Data Server regardless of I/O devices
specified in parameter Nos.20-23.
Make all paths in alarm states before the output, which is required to start the output to Data Server (See 0
in NOTE below).

Waveform data transfer failure signal WVTF<F0578.1> is “1” if the output fails because of, for examples,
no data Folder existing on Data Server, memory shortage, not in alarm states, and so on. After the cause
of failure is resolved

while

WVTF<F0578.1> is “1”, setting Waveform data re-output signal

WVROP<G0589.2> from “0” to “1” restarts the output in such cases.
Waveform data transfer failure signal is “0” in the following cases:
1)

When the re-output finishes normally.

When the next sampling is started.

When power is turned off.

Sequence of normal output is shown in Fig. 19.2.6 (a) and Fig. 19.2.6 (b), and that of output failure is
shown in Fig. 19.2.6 (c) and Fig. 19.2.6 (d).
