How to adjust
Increase the value within the range where no abnormal noise and no
vibration occur. If they occur, lower the value.
When vibration occurs by changing Pr1.01, change this value.
Setup so as to make Pr1.01 x Pr1.04 becomes smaller than 10000.
If you want to suppress vibration at stopping, setup larger value to
Pr1.04 and smaller value to Pr1.01. If you experience too large
vibration right before stopping, lower than value of Pr1.04.
Adjust this observing the positioning time. Larger the setup, faster
the positioning time you can obtain, but too large setup may cause
oscillation.
Setup this value within the range where no problem occurs. If you
setup smaller value, you can obtain a shorter positioning time, but
too small value may cause oscillation. If you setup too large value,
deviation pulses do not converge and will be remained.
Increase the value within the range where no abnormal noise
occurs.
Too large setup may result in overshoot or chattering of position
complete signal, hence does not shorten the settling time. If the
command pulse is not even,you can improve by setting up Pr1.11
(Feed forward filter) to larger value.
