 Zusammenfassung: The paper presents the current electronics design status of the MORFEO (formerly known as MAORY) Low-Order and Reference (LOR) WFS module. The LOR WFS Module is a subsystem of MORFEO and it implements the NGS WFS capabilities of the MCAO system. The LOR WFS module is hosted in the Green Doughnut: a volume shared with the MICADO SCAO system and embedded into the MICADO envelope. Both the optomechanics and electronics shall take into account the design constraints given by the shared environment. While the LOR devices are placed in the Green Doughnut, the subsystem control electronics modules are hosted inside two cabinets on the MICADO co-rotating platform. In this framework a continuous effort has been carried out to harmonize all the electronics design with the MICADO partners. In this paper we present the tasks of the LOR electronics and the selection of the actuators, cameras and sensors needed to implement the WFS. Moreover, we briefly provide a description of their foreseen positioning inside the two 19” cabinets. Then we focus on the description of the control electronics strategy which follows the ESO design guidelines, i.e. based on Beckhoff PLC and EtherCAT Fieldbus. We detail the analysis of all the hardware modules used to implement functions such as I/O signals, digital communication interfaces, motion control and sensor front-end. Finally, we discuss some preliminary results of the tests performed to evaluate the control strategies. This prototyping activity will be continued and broadened out during the incoming FDR.
