Posted 5 May 2021 Hi Guys, It is my first time to config Servo 2198-070-ERS, and there is a fault of No CST Master detected. I got recovery method of Clear the Fault. Configure a device to be the CST master. But I couldn't locate where I can configure it. Thanks in advance! Victor Share this post Link to post Share on other sites
Posted 5 May 2021 Depends on the type of controller and communications type of the servo. Usually, the CST is configured in the properties of the controller. Share this post Link to post Share on other sites
Posted 3 Feb 2022 This could be because Enable Time Synchronization is not enabled on the PLC controller. Share this post Link to post Share on other sites
Posted 3 Feb 2022 You may also need to configure time sync in the connection from a ControlLogix processor to the EN2T/3T/4T in the chassis. Share this post Link to post Share on other sites
