Perform installation and wiring correctly, and turn ON the power supply to check the operation of the individual Servomotor and Servo Drive.
This section explains the procedure that you perform to prepare the system for operation after installation and wiring of the Servomotor and Servo Drive are completed.
When you finished installation, wiring, and switch settings, and confirmed that the status was normal after turning ON the power supply, perform test run.
If any problems should occur, take the following actions.
This function outputs a warning signal to enable you to check a state such as an overload before an error occurs.
If the Servo Drive detects an abnormality, it outputs an error (/ERR), turns OFF the power drive circuit, and displays the error number (main and sub) on the front panel.
If an error occurs in the Servo Drive or operation, identify the cause of the error and take appropriate measures as shown below.
This section lists and describes the error event codes that you can see in Sysmac Studio.
