11.2 Improving the Servo-Control Settings<br />

When all the machine axes have been integrated, the settings can be improved.<br />

11.2.1 Time Constant<br />

It is recommended to use the same time constant on all the main axes. The largest time constant is used for these<br />

axes.<br />

The equations to be used are:<br />

11 - 6 en-938818/4<br />

KVAR (for a 9 V reference) = 29491 / VMAX x Τ x k<br />

EMAX = VMAX x Τ x 11/10/k<br />

Axis @ Τ VMAX KVAR EMAX<br />

0<br />

1<br />

2<br />

3<br />

4<br />

5<br />

6<br />

7<br />

8<br />

Modify the settings on each axis if these values are optimistic.<br />

Enter the values of KVAR in the words of P21.<br />

Enter the values of EMAX in the words of P23.<br />

Enter the values of T in the words of P56.
