Tuning becomes easier by graphically displaying servo error amount and

WAVEFORM
The following two types of waveform diagnosis functions are supported:
DIAGNOSTIC
FUNCTION
(1) One-shot type
The one-shot type waveform diagnosis function can graphically
display, as a waveform, any variation in those data items listed below.
The start of data sampling can be triggered by the rising or falling edge
of a machine signal. This function facilitates the adjustment of the
servo and spindle motors.
a. Error, pulse distribution amount, torque, speed, current, and
thermal simulation data for the servo motor of each axis
b. Composite speed for the first, second, and third axes
c. Spindle motor speed and load meter value
d. On/off state of a machine signal specified with a signal address
(2) Storage type
The storage type waveform diagnosis function enables the storing
of any variation in the data items listed below and, if a servo alarm
occurs, the graphical display (as a waveform) of the stored data. The
end of data sampling can be triggered by the rising or falling edge
of a machine signal. This function facilitates the estimation of
erroneous locations. Stored data can be output via the reader/punch
interface.
a. Error, pulse distribution amount, torque, speed, current, and
thermal simulation data for the servo motor for each axis
NOTE
1
To output stored waveform data, the optional reader/punch
interface must have been installed.
2
The waveform diagnosis function is enabled when bit 0
(SGD) of parameter No. 3112 is set to 1. Note, however, that
a graphics card is necessary to display waveforms.

D Drawing a waveform for
The one-shot type waveform diagnosis function draws a waveform for a
one-shot type waveform
specified data item in real time as the data is sampled. The sampled data,
diagnosis
however, is not stored and thus cannot be output later.
To sample data for one-shot type waveform diagnosis, press the
[START] key on the WAVE DIAGNOS. (GRAPHIC) screen. Then, data
is sampled when the specified start condition is satisfied. Data sampling
continues for the specified period.

Pressing the [SATART] soft key starts data sampling. While sampling
is being performed, SAMPLING blinks at the top of the screen. Once data
sampling has been completed, a waveform is automatically displayed.

condition. The maximum data width for storage type waveform diagnosis
diagnosis
is 32760 ms. Data must be sampled before starting drawing. The next
page explains sampling in detail.
Pressing the [START] soft key loads stored data. While the data is being
loaded, SAMPLING blinks at the top of the screen. Once the data has
been loaded, a waveform is displayed. The date on which the data was
stored is displayed at the top left of the screen. If the [START] soft key
is pressed while data is being stored, storage is stopped and the waveform
for the data stored up to that point is displayed. The WAVE DIAGNOS.
(MEMORY) screen indicates whether data is being stored.

axes, position the cursor to the data item to be set, enter the names of
the axes for which data will be sampled for that data item, then press
[SELECT] or

. The axis names are displayed to the right of the
data items.
Example) XYZ + [SELECT] or

(5) Once the sampling axes have been selected, the sampling period for
each axis is displayed. Subsequently pressing the [START] soft key

To change the sampling axes, enter new axis names then
press the [SELECT] soft key. Pressing the [SLELCT] soft
key without entering an axis name results in no sampling

D Storage data parameters
(1) Storage stop condition
100: Stops data storage upon the issue of a servo alarm.
101: Stops data storage upon the issue of a servo alarm or the
detection of the rising edge of the trigger signal.
102: Stops data storage upon the issue of a servo alarm or the
detection of the falling edge of the trigger signal.
The maximum stored data width is 32760 ms. If the storage stop
condition is not satisfied within 32760 ms, data is overwritten, starting
with the oldest data.
Parameter No. 3120 can be used to delay data storage being stopped
by a specified period (ms), after the issue of a servo alarm.
(2) Trigger: Set the PMC address and bit for the signal used to trigger the
stopping of data storage, when 101 or 102 is set for the stop condition.
Example) G0007.2: ST signal
