(4) Full utilization of level-up HRV control
Level-up HRV control allows the velocity gain to be increased by
decreasing the current control period. In addition, by optimizing each
element of the servo system, level-up HRV control can be fully utilized
to reduce machining figure errors. (See Subsec. 3.4.1.)
NOTE
Set the same current control period for two axes(*)
controlled by the same DSP.
For example, an axis for which No. 1023 = 1 is set,
and an axis for which No. 1023 = 2 is set are
controlled by the same DSP. So, the same current
control period must be set for these axes.
* An axis for which an odd number is set with the servo
axis number parameter (No. 1023), and an axis for
which the subsequent even number is set with the
same parameter are controlled as a set by the same
DSP.
