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.
