MONORAIL AMSA 4B is an integrated magneto-resistive measuring system for distance measurement based on the MONORAIL BM profile ball guideway with an analog voltage interface. These products are preferred for use in applications that make major demands on travelling speed and accuracy. No additional assembly or adjustment of the measuring system is required, which is reflected by cost savings in machine design, manufacture and servicing.
The accuracy and process reliability of the machine are also improved. The sturdy housing for the read-head has a complete wiper system consisting of longitudinal and cross wipers, which provide optimum protection for the measuring system. The AMSA 4B version has an analog voltage interface of 1 Vss for connection to all standard control systems.
Frequently Asked Questions about the AMSA System from SCHNEEBERGER
Is a calibration required after installing an AMS system?
The absolute position is available after a reference run following power-up.
Does the exact absolute position need to be restored when replacing components?
When replacing read heads, a deviation of a few tenths of a millimeter is possible. If higher accuracy is required, a correction in the control parameters is necessary.
Does the read head need to be aligned during installation?
No alignment of the read head is necessary. It is sufficient to attach the read head using the screws provided.
How much does the signal period of 200 µm affect the system's deviation?
The periodic deviation is less than 0.8 µm.
How do external fields from motors and rotary tables affect the built-in scale?
The scale is protected inside the rail. The external fields are short-circuited by the rail and the surrounding environment, so they have no impact on the scale.
What should be considered when using linear motors?
The risk that tools or chip nests will direct a magnetic flux through the scale is avoided by installing the scale on the opposite side of the linear motor.
What should be considered during installation?
AMS rails are installed without the use of magnetic lifting tools to avoid leaving residual magnetism in the rail.
What accessories are used with the AMS?
The complete range of MONORAIL MR and MONORAIL BM can be used with AMS. However, sheet metal wipers from the standard program cannot be used.
Does an AMS axis require more installation space than an axis without AMS?
In cross-section, compact carriages result in a minimally larger profile. In the direction of travel, the AMS is positioned between two carriages. If there is sufficient space between the carriages, the total length of the rail does not increase.

The MONORAIL AMS 4B is an integrated magneto-resistive measuring system for distance measurement based on the MONORAIL BM ball profile guideway. In measuring terms, the AMS 4B is the same as the AMS 3B; it offers the same performance in terms of assembly, cost savings, accuracy and process reliability. AMS 4B products are preferred for use in applications that make major demands on travelling speed and require good resistance to acceleration and vibration.
