Vibration suppression control tuning mode (advanced vibration suppression control)
This parameter cannot be used in the speed control mode.
The vibration suppression is valid when the parameter No. PA08 (auto tuning) setting is
" 2" or " 3". When PA08 is "
invalid.
Select the setting method for vibration suppression control tuning. Setting this
parameter to " 1" (vibration suppression control tuning mode) automatically
changes the vibration suppression control - vibration frequency (parameter No. PB19)
and vibration suppression control - resonance frequency (parameter No. PB20) after
positioning is done the predetermined number of times.

setting changes to " 2". When the vibration suppression control tuning is not
necessary, the setting changes to "
the initial values are set to the vibration suppression control - vibration frequency and
vibration suppression control - resonance frequency. However, this does not occur
when the servo off.
For manufacturer setting
Do not change this value by any means.
Feed forward gain
This parameter cannot be used in the speed control mode.
Set the feed forward gain. When the setting is 100%, the droop pulses during operation
at constant speed are nearly zero. However, sudden acceleration/deceleration will
increase the overshoot. As a guideline, when the feed forward gain setting is 100%, set
1s or more as the acceleration/deceleration time constant up to the rated speed.
For manufacturer setting
Do not change this value by any means.
