Figure 10
The vertical position is altered every 20 s by stepping the motors with two half-steps (0.025 µm) while the absolute Renishaw encoder is sampled. Overlaid is also the state of the motion where zero indicates that the motion has come to a stop and a measurement could start. The 0.025 µm step is well resolved but a variation in absolute position is present. Motions are within the deadband of the closed loop so no corrections are activated in this case.
