*1 The velocity loop proportional high-speed processing function
restricts the use of auxiliary functions that suppress vibration in
the stop state. If vibration in the stop state poses a problem, select
the acceleration feedback function.
*2 With the 90A0/D and subsequent editions, this function can be
used together with the velocity loop proportional high-speed
processing function.
*3 This function cannot be used with the velocity loop proportional
high-speed processing function.
<4> Setting for suppressing vibration in the stop state:
A stop occurs within a backlash, and the load inertia decreases.
Accordingly, the velocity loop can easily oscillate. So, set auxiliary
functions for suppressing vibration in the stop state in advance.
Function for changing the proportional gain in the stop state
(50%, 75%)(*2)
N pulse suppression function(*3)
With the 9080/P and subsequent editions, the cutting feed/rapid traverse
velocity loop gain switch function can be used to decrease the gain
during rapid traverse and in the stop state. If vibration in the stop state
poses a problem, decrease the rapid traverse velocity loop gain to a level
that does not affect the behavior during rapid traverse.
<5> When using level-up HRV:
When using level-up HRV, set the current control period and adjust the
vibration-damping filter according to Subsec. 3.4.1, "Level-up HRV
Control Adjustment Procedure."
