<4> In the displayed dialog box, press the [Add] button. Then waveform data
is analyzed, and candidates of the compensation parameters are
registered. For “2/span” and “4/span” items in the dialog box, they
correspond to 1.5 times and 3 times smoothing compensation per pole
pair. “6/span” is not used in smoothing compensation for synchronous
built-in servo motor.
<5> The compensation parameters slightly vary depending on the
measurement situation. So, repeat a data measurement and a press of
the [Add] button several times in a similar manner while keeping the
dialog box open. (Up to five candidates can be registered.)
If the displayed values include an extremely different value, uncheck the
corresponding check box on the leftmost side of the list so that the value
is not taken into account in the final compensation calculation.
<6> Finally, press the [Calculate] button for each of the forward and
backward directions. Then, smoothing compensation parameters are
displayed.
<7> When the target axis for parameter transfer is selected in "Parameter
change", and the [Send param.] button is pressed, the presented
parameters for synchronous built-in servo motor smoothing
compensation are set in the CNC.
<8> Measure TCMD again to confirm the effect of smoothing compensation.
