Driver fault at startup

Hi all, i am using this master ethercat through the implementation in ros2 ethercat driver, on an elmo platinum quartet solo driver. This is a driver that has 4 axis on a single ethercat device. When i launch my application trying to change the state machine to OP, the driver completely loses connection(ethercat slaves wont show any device), and still shows no device until i close the application. Up to now i am trying to use a single axis out of 4, and i am configuring it corrrectly. is this due to the master ethercat implementation ? how can i debug such a case ? Thanks
