It is helpful to have as much information as possible so that the correct motion device and driver / controller can be identified. Motorised micropositioners and piezo driven nanopositioners are defined in a slightly different way. See the table below.
| Nanopositioner / Piezo (NP) | Motorised Micropositioner (MP) | Comments |
| Travel Range | Travel Range | NP up to 1.5mm, MP up tp 300mm |
| Minimum Incremental Motion |
Minimum Incremental Motion | NP <0.1nm, MP <4nm possible |
| Repeatability | Repeatability | Bi-directional or Uni-directional? |
| Number of Axes | Number of Axes | Up to 6 integrated in one stage possible |
| Orientation | Orientation | Important when considering loading |
| Applied Load | Applied Load | Dynamic or Static? |
| Dimensions of Applied Load | Dimensions of Applied Load | COG (Centre of Gravity) can be useful to know |
| Static or Dynamic Application | Velocity | Up to 500mm/s possible |
| Continuous Waveform or Step and Settle? | Constant Velocity or Step and Settle? | |
| Open Loop or Closed Loop? | DC, Stepper or Piezo Motor Driven? | NP Open Loop much faster than Closed Loop |
| Environmental Issues? | Environmental Issues? | Temperature, Pressure, Humidity, Particulates |
| Vacuum, Non Magnetic, Radiation Hard? | Vacuum? | Specify vacuum level |
| Controller Analogue or Computer Driven? | Controller PCI Bus or Standalone? | RS-232, USB, PCI, PIO Interfaces |
Although it is not vital to have all the above information, the more that can be provided the easier it is to find the right solution.
Once you have defined as much of the requirement as you can please either send us the details or telephone us to discuss the application.
An on site visit to discuss the application or to demonstrate equipment can be arranged if appropriate.
