Abstract
MAVIS (MCAO Assisted Visible Imager and Spectrograph) is a new instrument that will operate on the UT4 of the ESO Very Large Telescope (VLT), delivering comparable angular resolution in the optical to that delivered by ELTs in the infrared. The MAVIS core is represented by a multi-conjugate Adaptive Optics Module (AOM) designed to feed an Imager, a Spectrograph and a visiting instrument, all operating in the visible range. The project is now in the preliminary design phase and will be commissioned in 2027 according to the current plan. We present the current status of the MAVIS AOM instrument control electronics that will manage all the motorized functions and auxiliary sensors, focusing on the main design concepts and the preliminary prototyping activities. The design includes ESO standards and Commercial Off-The-Shelf (COTS) industrial components organized in a modular architecture to simplify the AOM preliminary integration activities, planned simultaneously in different sites. Important guidelines to the design are the attention to the overall reliability and maintainability and the minimization of risks. Almost all the motorized functions are implemented adopting preassembled industrial motorized stages. For the tracking axes, a prototyping activity has been envisaged during the design phases, in order to assess the adopted solutions are compatible with the positioning and tracking requirements.
