15.1.2 Waveform diagnosis parameters (storage type)
(1) Display start condition
100 : Draws a waveform for the stored data.
(2) Sampling period: Invalid
(3) Trigger: Invalid
(4) Data number: The table below lists the numbers of the data items for which
a waveform can be displayed (n = 1 to 8). Numbers for which no data is
stored cannot be specified.
Data No.
Description Units
00 Does not display a waveform. –
0n Servo error (8 ms) for the n–th axis
(positional deviation)
Pulses
(detection units)
1n Pulse distribution for the n–th axis
(move command)
Pulses
(input increments)
2n Torque for the n–th axis (actual cur-
rent)
% (relative to maximum
current)
5n Actual speed for the n–th axis min
–1
6n Command current for the n–th axis % (relative to maximum
current)
7n Thermal simulation data for the
n–th axis
(when the PRM3121 is set to 0.)
% (OVC alarm ratio)
111 Load meter for the n–th spindle
(when the PRM3121 is set to 1.)
% (relative to maximum
output)
(5) Data units: Weight of data when 1 is specified. The data units are
automatically specified for each data item and need not be set unless the
units must be changed for some reason.
[Valid data range] 1 to 1000
[Unit] 0.001
(6) Signal address: Invalid
