5.4. Setting Filters (Tuning Level 2)
5.4. Setting Filters (Tuning Level 2)
l Setting low-pass filter (Parameters FP and FX) will decrease resonant noise level. Unit of the
setting data of the parameters of FP and FS is frequency [Hz]. If the parameters of FP and FS are
set under 100 [HZ], the servo may become unstable, thus resulting Motor hunting or adverse
effect on positioning.
l The low-pass filters shall be set after adjusting the gains (after the automatic tuning or the
manual tuning).
l Operate the Motor by the demonstration program (SP/AJ) for setting the low-pass filters.
[Follow the procedure 1] to 7] described in "5.2.4. Trial Running (Tuning Level 1)" to operate
the Motor.]
l A master controller shall be used to give the command when the System is in the torque or the
velocity control mode.
1) Start the adjusting program of the parameter FP.
The screen displays the message as shown below and you can change the FP setting up and
down using the (+) and the (-) keys. (Actually the FP parameter differs with a load inertia and
rotation angel.)

pressed. (VI changing resolution)
(4) Response index number: Smaller number denotes better response.
(5) Positioning index number: Smaller number requires shorter time to complete a
press of the (+) or the (-) key to 1/10 of current setting.
Input of the BS key will alter the changing resolution of VG for one
press of the (+) or the (-) key to 10 times of current setting.
