Function Description
The disturbed waveform begins when the drive reaches Speed Agree (bandwidth adjustable
by parameter L4-02). The disturbed waveform rides on top of the base frequency reference
for the traverse drive.
Adjusting the frequency reference of the master drive while the disturbed waveform is active
produces an output that is the frequency reference waveform summed with the disturbed
waveform.
The dithering is a triangle waveform with amplitude and slope set by P1-02, P1-04, and
P1-05. The traverse drive also has a jump in the dithering waveform set by parameter P1-03.
The anti-phase output signal is the disturbed portion of the traverse frequency reference with
the signal inverted. Only the triangle portion of the disturbed waveform is used for the anti-
phase output; the jump is ignored.
The Traverse application software has three monitors: U7-04, Base Slave Frequency, outputs
the frequency reference of the drive before the disturbed waveform is applied; U7-03, Ripple
Slave Frequency, outputs the anti-phase of the disturbed portion of the waveform summed
with 50% of Maximum Output Frequency parameter E1-04; and U7-02, Absolute Slave
Frequency, outputs the anti-phase of the disturbed portion of the waveform summed with
U7-04.
All three monitors can be set to analog outputs, however U7-02 or U7-03 would generally be
used as an analog output going to the slave (spindle) for the frequency reference. U7-02
provides the slave with a complete reference signal. U7-03 is used as a dither reference if the
slave should use its own base frequency reference (as shown in the
).
To compensate for system delays, U7-02, U7-03, and U7-04 can be set to lead or lag the
traverse control output by 0 to 12 scans (0 to 24 ms) using parameter P1-06.
