There are two different load ratings for these stages.
Ball slides:
These have precision steel balls rolling in the tracks.
They are the least expensive, loads up to 28Kg.
Locking options
Posi-lock:
Allows locking of the carriage in place with a friction locking mechanism.
Cross roller slides:
These have the same dimensions but have rollers allowing the slide to carry large loads and absorb greater moment loads up to 54Kg.
Locking micrometer:
Locking of the micrometer to fix the micrometer setting.

End of Travel and/or Home Position switches can be installed onto these linear stages – please see the drawings of the brackets that attach to the stages that result from this requirement.
The End of Travel switch kit comes with two switches mounted to the base at each end – there are two flags mounted to the carriage. These flags are adjustable for either the full range of travel or a limit amounted. The Home Position switch comes with one flag mounted to the base in the centre – with an adjustable flag mounted to the carriage, allowing the home position to be set at any point.
The switches are photoelectric sensors that operate on a supply voltage of 5 to 24V DC. The repeatability is 5 microns, the response time is 100 microseconds. The sensors are available in both NPN and PNP outputs. Quick fitting hook up cable (3 metres) provided.

Our motorised linear stages are precise, heavy duty and available from 25mm stroke to 800mm.
They can be easily controlled either with an Intelligent motor (this is a motor with an inbuilt driver and controller) or with a motor and one of our motion controller stages.
Programming for both the intelligent motor (less expensive) and the motion controllers is very simple and we provide free software and sample source code for Labview, VB, C++, OSX etc. It is also possible to download a stand-alone programmed to the device so it can run independently of a host.
We also offer a Joystick controller.
The stages can be readily supplied in X, XY, XZ and XYZ configurations and can also be used with our range of rotary tables (L3550 to L3562).

Stepper limitations
For all of their advantages, stepper motors have a number of limitations which can cause significant implementation and operational issues depending on your application. Stepper motors do not have any reserve power. In fact, stepper motors lose a signifi cant amount of their torque as they approach their maximum driver speed. A loss of 80% of the rated torque at 90% of the maximum speed is typical.
Stepper motors are also not as good as servo motors in accelerating a load. Attempting to accelerate a load too fast where the stepper cannot generate enough torque to move to the next step before the next drive pulse will result in a skipped step and a loss in position. If positional accuracy is essential, either the load on the motor must never exceed its torque or the stepper must be combined with a position encoder to ensure positional accuracy.
Stepper motors may also suffer from vibration and resonance problems. At certain speeds, partially depending on the load dynamics, they may resonate and be unable to drive the load. This may result in skipped steps, stalled motors, excessive vibration and noise.
Servo limitations
Servo motors are capable of delivering more power than stepper motors, but do require much more complex drive circuitry and positional feedback for accurate positioning. Servo motors are also much considerably expensive than stepper motors and are often harder to find. Servo motors often require gear boxes, especially for lower speed operation.
The requirement for a gearbox and a position encoder makes servo motor designs more mechanically complex and increases the maintenance requirements for the system. To top it all off , servo motors are more expensive than stepper motors before adding on the cost of a position encoder.
Summary
Selecting the best motor for your application depends on a few key design criteria for your system including cost, positional accuracy requirements, torque requirements, drive power availability, and acceleration requirements. Overall, servo motors are best for high speed, high torque applications while stepper motors are better suited for lower acceleration, high holding torque applications as well as generally being less expensive and easier to control.

Introduction
The software is the main interface for setting up the motor for a specific application. The program offers the following features:
Command toolbox description
The toolbox used for the programming covers 14 different command types. The idea for the commands is to have an easy access to the most common functions in the motor. Some functions seem to be “missing” at first sight but the button “Set register in the quickstep motor” or “Wait for a register value before continuing” gives direct access to 50 function registers. In total this gives a very powerful programming tool since >95% of a typical program can be built using the simple command icons and the last part is obtained by accessing the basic motor registers directly if required.

Run-out
The displacement of a measure sensor placed on the surface of the rotary table.
Applied loads
These cause small deformations in the stage bearings and are dependent on the stiffness of the stage, the bearings and the stability and flatness of the mounting surface.
Hysteresis errors
The difference between the control and instructed position.
Backlash errors
Errors caused by the reversal of the direction of travel affected by clearance in the drive chain.
Encoder errors
Imperfections in the operations of the encoder (if present).
