Chapter 4 Operation
Depending on the shape of the mass and the accelerations and velocities used the
values quoted above may require adjustment to provide optimum performance.
The values quoted above are the maximum values recommended to avoid over
current errors. These values are a guideline only, and depending on the shape of the
mass and the velocities used, these values may require further adjustment,
particularly if the stages are mounted in an XY configuration.

Position PID Settings Summary
Stage overshoots the intended position - reduce the integral term, and increase the
derivative and proportional terms.
Stage fails to attain final position - increase the integral and proportional terms.
Motion is unstable - reduce the proportional and integral terms, increase the
derivative term.
Stage sounds noisy - reduce the derivative term.
Please see the handbook supplied with the controller, for more information on
changing these settings
