Tuning becomes easier by graphically displaying servo error amount and
torque command, etc. (Graphics control circuit is required).
The following two types of waveform diagnosis functions are supported:
(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
The waveform diagnosis function is enabled when bit 0
(SGD) of parameter No. 3112 is set to 1. Note, however, that
a graphics control circuit is necessary to display waveforms.
(1)Set a parameter to utilize the servo waveform diagnostic function.

3112
#6 #5 #4 #3 #2 #1 #0
SGD
#0(SGD) 0 : Do not display servo waveform (usual graphic display).
1 : Displays servo waveform (usual graphic display function cannot be
used).
(2)Turn off the power once and turn it on again.
