The integrated absolute value measuring system from Rexroth sets up in a matter of minutes
Bosch Rexroth makes it even easier to set up the new IMS-A measuring system integrated into linear guides with the introduction of the new DRIVE-CLiQ* interface. Plug it in, determine the measurement section and you’re done.This Ethernet-based interface automatically recognizes the electronic nameplate of the highly accurate and robust new absolute value measuring system.
Since the IMS-A introduction on the market, it has been possible to set up within minutes with HIPERFACE** and the Rexroth IndraDrive. Complemented by the SSI interface, IMS-A also provides universal support for machine tools, additive production processes and other applications requiring high levels of precision.
Combining guiding and measuring functions in a single component significantly reduces the mechanical installation effort in the machine. The DRIVE-CLiQ* interface also shortens the electrical start-up when it is used with Siemens drives and controls. With the Plug & Play encoder system, the person performing the setup merely has to determine the respective zero point of the machine and the measurement section. DRIVE-CLiQ* retrieves diagnostic information as well as enables all other information to be transferred automatically from the electronic nameplate of the IMS-A.
The absolute position is transferred with a resolution of 25 nm, while the repeatability is better than +/- 0.25 μm. The integrated scale is available at an accuracy of up to +/- 3 μm/m which rivals a glass scale. With the IMS-A, engineers can use several runner blocks on a profiled rail independently and without any accuracy limitations. Even after a power failure, the measuring system still reports the exact position of the axis without a homing cycle.
Integrated into the linear guides, the absolute position measuring system operates without contact and is therefore wear-free. Even in working spaces with coolants, dust, shavings and other contaminants, the IMS-A does not require elaborate energy wasting air purge systems. The regular replacement or cleaning work that would usually be necessary for glass scales in these environments is no longer required which means less machine downtime. In addtion, the measuring system is not sensitive to magnetic fields or vibrations and shocks. The sensors and evaluation electronics are located in an IP67 protective housing on the end face of the runner block This allows design engineers to save space normally needed for external measuring systems. Rail guides equipped with the IMS-A fit into existing machine designs without any constructional alterations in virtually every application.
