The European XFEL project is a 4th generation X-ray light source. The undulator systems SASE 1, SASE 2 and SASE 3 are used to produce photon beams. Each undulator system consists of an array of undulator cells installed in a row along the electron beam. The motion control of an undulator system is carried out by means of industrial components using an EtherCAT fieldbus. One of its features is motion synchronization for undulator cells which belong to the same system. This paper describes the technical design and software implementation of the undulator system control providing that feature. It presents the results of an on-going proof-of-principle study of synchronous movement of four undulator cells as well as study of movement synchronization between undulator and phase shifter.
