25.10 WAVEFORM DIAGNOSIS FUNCTION
This function traces data such as a servo position error, torque, and a
machine signal and shows a change in the data as a waveform. This
facilitates the adjustment of a servo motor and a spindle motor and
finding of a possible cause in a problem.
This function traces the following data.
(1) Servo-related items
Position error of a servo motor along each axis, pulse count after
distribution, torque, pulse count after acceleration and
deceleration, actual speed, specified current, and thermal
simulation data
(2) Combined speed for all axes
(3) Spindle-related items
Spindle-motor speed and load meter indication
(4) State of on ("1")/off ("0") of machine signal
A total of four items among the servo-related items, the combined
speed for all axes, and the spindle-related items, and four machine
signals can be traced at a time.
The waveforms of all traced data items can be displayed at the same
time.
