Table 1

A typical lookup table organisation
x
–200 –160 –100 –61 0
–160 –121 –40 0 61
y –100 –40 0 40 100
–61 0 40 121 160
0 61 100 160 200

The x axis (horizontal with respect to the page orientation) is the position error, and the y axis (vertical) is the speed of the motion. The appropriate cell value can be directly used to feed the DAC for a voice coil voltage.
