• Operation

The specifiable values are as shown in Table 1.9.1.4 (a), Fourier graph operations.

Remarks

Draws of the Y-time graph correspond to those of the Fourier graph on

31 : Fourier

a one-to-one basis. The Fourier operation can be set only when the

corresponding Y-time graph draw is effective.

Setting the scale screen

• Start point

Set gain and phase data values for the center of the graph.

• Division

Set the value of one grid.

• Frequency

Set the minimum and maximum values of the horizontal axis. Since the unit is dependent on the time

range selected for the Y-time graph, 1 is not necessarily equal to 1 Hz.

(Example)

When a 0.1-second time range is selected, 1 is equal to 1 Hz.

1.9.1.5 Bode graph

This graph displays a Bode diagram for the measurement data in the form of a horizontal axis logarithm

graph.

Only one draw can be displayed at a time.

Displaying and setting the Bode graph

Procedure

To display the Bode graph, set the parameters for automatic vibration (disturbance input function) using

servo software.

The procedure for displaying the measurement data is described below.

Press the

function key.

Press and hold this key until [PARAMETER] appears.

Set the following parameters.

No.2326 (Disturbance input gain)

Recommended value: 500

No.2327 (Start frequency of disturbance input) Recommended value: 10

No.2328 (End frequency of disturbance input) Recommended value: 1000

No.2329 (Number of disturbance input measurement points）

Recommended value：3

When bit 7 (DSTIN) of parameter No. 2270 changes from 0 to 1, disturbance input starts. This

operation needs to be performed to start measurement, so a program that changes bit 7 (DSTIN) of

parameter No. 2270 from 0 to 1 with program data input (G10) must have been created in advance.

Programming example: When the Z-axis (third axis) is vibrated (when bit 4 (G1B) of parameter 3454 is

O1234

N1G10L52 ;

Setting the operation and graph setting screen

The operation and graph setting screen lets you specify graph settings.

• Operation

The specifiable values are as shown in Table 1.9.1.5 (b), Bode graph operations.

An operation cannot be specified if it does not meet the graph display conditions defined in Table

1.9.1 (c), Bode graph conditions.

#3 ACREF Adaptive resonance elimination filter

0: Disabled

1: Enabled

When this function is enabled, disable it temporarily and then use the disturbance input

function.

(This is because the resonance elimination filter changes in response to the vibration of

the axis even if the vibration is caused by the disturbance input function.)

#4 DSTMV Usually, set 0.

#5 DSTWAV The input waveform of disturbance input is:

0: Sine wave.

1: Square wave.

Usually, set 0.

#6 DSTTN Disturbance is:

0: Input for one axis only.

1: Input for both the L and M axes.

Usually, set 0. To be set only for the L axis side of synchronous axes or tandem axes.

#7 DSTIN Disturbance input

0: Stop

1: Start

Disturbance input starts on the rising edge from 0 to 1.

1.10 MAINTENANCE INFORMATION SCREEN

The maintenance information screen is provided to record the history of maintenance performed by a

service person of FANUC or machine tool builder.

The screen has the following features:

• MDI alphabetical input is allowed.

(Half-size kana input is for Japanese display only.)

• The recording screen can be scrolled in units of lines.

• Edited maintenance information can be input and output.

• Records are stored in Flash ROM.

• Double-byte (shift JIS) codes can be displayed.

1.10.1 Displaying the Maintenance Information Screen

Press function key

Press continuous menu key

several times until soft key [M-INFO] is displayed.

Press the soft key [M-INFO]. The maintenance information screen appears.

When selected, the maintenance screen shows the latest information.

The status (mode, number of empty character spaces, cursor line, column number) is displayed at the

bottom of the screen.
