7.1.3 Operation of Servo trace
(1) How to open Servo trace screen
A-1 Push SYSTEM
key on MDI.
A-2 Push [ ] of Soft-key, and push [SV-PRM] of soft-key.
A-3 Push [SV.TRC] of soft-key, and push [(OPRT)].
Then [TRACE] and [TRNSF] of soft-key display in Servo trace screen.
(Note) [TRNSF] displays only in EDIT mode.
(2) How to Servo trace
A-1 Set the parameters of sampling period, sampling number, and kinds of trace data.
And set program number stored trace data.
A-2 If you want to set initial value of summation data (B4, B5, and B8) to 0, move at initial position you want,
and push CAN
key on MDI in Servo trace screen. Refer to A-6 (Note).
A-3 In Servo trace screen, push [TRACE] of soft-key to trigger on timing when you trace.
When Servo trace starts, “LSK” displays under right screen.
If “LSK” does not display, check parameters.
When Servo trace finishes, “LSK” erases. So far the trace data is stored in the memory of servo DSP.
A-4 Push [TRNSF] of soft-key in Servo trace screen in EDIT mode.
Then trace data are transmitted to program area of NC, so called C-MOS memory.
“EDIT” displays under left screen during transmitting.
When data transmission finishes, “EDIT” erases.
A-5 Well you get the data created in your selected program number as the following form.
Onnnn ; ← “nnnn” is selected by No.1860.
Pxxxxx ; ← “xxxxx” is decimal notation with sign.
⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅
Pxxxxx ;
%
A-6 The trace data is a parts program form already familiar with, and you can output the data to your
computer through RS232C and analyze the data in your computer.
A-7 If you cancel the trace on the way, push CAN
key on MDI in Servo trace screen.
(Note) At cancel, summation data (B4, B5, and B8) are set to 0.
7.1.4 Examples of analysis of trace data
(1) Case of Lead cam lathe
A-1 Select Position feedback (No.2027 = 1), and trace the
data.
A-2 Output the selected Program with the trace data to your
computer through RS232C.
A-3 Sum and draw this data using the tool such as Excel,
then result as Fig. 7-1-4
A-4 By calculating the subtraction “πD•tanθ” from the center of this marked point “X”, you can analyze a
motor position on Lead surface. (D : Lead cam’s diameter, θ : Lead angle)
