(1) Switching between the damping frequency and damping filter setting is performed at the rising edge of the
command that causes the number of command pluses per command detection period (0.125 ms) (at
upstream of position command filter) changes from 0 to any other value while the positioning complete is
being output.
Even if the control mode is changed to position control after changing the damping frequency and
damping filter settings during velocity control or torque control, the setting is not changed.
Especially, at higher damping frequency, or if it becomes disabled, and wider positioning complete range
is set up, and if large pulse (area is equivalent of time integration of the value of position command at
upstream of the filter minus the value of position command at downstream of filter) remains in the filter
during switching, it is rapidly discharged upon switching and returns to original position, and the motor will
move at a speed higher than normal command velocity.
(2) There is delay from setting change of damping frequency or damping filter to internal computation and
application of new setting values. If the switching described in (1) occurs during this delay time,
application of new value will be suspended.
