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 SV.Pr11, change this value.

Setup so as to make SV.Pr11 x SV.Pr14 becomes smaller than 10000. If you

want to suppress vibration at stopping, setup larger value to SV.Pr14 and

smaller value to SV.Pr11. If you experience too large vibration right before

stopping, lower than value of SV.Pr14.

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. You can improve by setting up

SV.Pr16 (Feed forward filter time constant) to larger value.

Adjustment in Position Control Mode

Position control of MINAS-A4P series is described in Block diagram of P.224.
Make adjustment in position control per the following procedures.

(1) Set up the following parameters to the values of the table below.

(2) Enter the inertia ratio of SV.Pr20. Measure the ratio or setup the calculated value.
(3) Make adjustment using the standard values below.
