6. STATUS DISPLAY BY SELF–DIAGNOSTIC DISPLAY
133
2: Starts data collection on a falling edge of a trigger signal after the
[START] soft key is pressed. Data is collected for a specified
sampling period, after which the data is plotted.
Sampling period: Sets the period during which data is to be collected.
Setting range: 10 to 32760
Units: 1 ms
Trigger: Sets a PMC address and bit. Set this item when 1 or 2 is specified
for the display start condition. This item specifies a trigger for
starting data collection.
Example: G0007.2: ST signal
Data number: The table below lists the numbers of data subject to
waveform display. A number from 1 to 8 can be entered in
the squares (n) of the data numbers below.
Data No.
Description Units
00 No waveform is displayed. –
0n Servo error along the n-th axis (8 ms)
(position deviation)
Pulses (detection units)
1n Number of pulses distributed to the
n-th axis (move command)
Pulses (increment system)
2n Torque value for the n-th axis
(actual current)
% (ratio to the maximum
current)
3n Servo error along the n-th axis (2 ms)
(position deviation)
Pulses (detection units)
5n Actual speed along the n-th axis RPM
6n Current command for the n-th axis % (ratio to the maximum
current)
7n Thermal simulation data for the n-th
axis
% (OVC alarm ratio)
90 Combined speed along the first,
second, and third axes
Pulses (increment system)
99 On/off state of the machine signal
specified with a signal address
None
10n Actual speed of the spindle along the
n-th axis
% (ratio to the maximum
speed)
11n Load meter for the spindle on the n-th
axis
% (ratio to the maximum
power)
161 Difference in position error calculated
on the spindle basis
Pulses (detection unit)
Data units : Weighting used when the data subject to analysis is 1. This
item is set automatically. Set this item only when different units
are to be used.
Setting range: 1 to 1000
Units: 0.001 increments
Signal address: PMC address and bit number. Set this item when the data
number 99 is specified. The example given in the trigger
item, above, applies.
(b) Memory-type waveform diagnosis (parameter)
Display start condition
100: Plots data sampled in memory type mode.
Sampling time: Not applicable
Trigger: Not applicable
Data number: The table below lists the numbers of data subject to
waveform display. A number from 1 to 8 can be entered
in the squares (n) of the data numbers below. No number
can be set for data that has not been saved.
