Troubleshooting8-88.2.3 Motor Does Not Rotate/Move (Output LED Flashes or is ON) Solution 1: For servo motorCheck to make sure the servo on input is set to “ON”. Solution 2Check to make sure the power supplies for the servo amplifier and motor driver are ON. Solution 3Check to make sure the servo amplifier and motor driver are connected to the unit correctly. Solution 4Check to make sure the settings for the pulse output method (CW/CCW method or Pulse/Signmethod) are appropriate.8.2.4 Motor Does Not Rotate/Move (Output LED is OFF) SolutionReview the program.Point to check• Check to make sure the I/O numbers are appropriate.• Check non-rewriting of the start flag in the program.• Check the input valid logic of the over limit switch. In this case, the error LED flashes.8.2.5 Rotation/Movement Direction is Reversed Solution 1Check to make sure the servo amplifier and motor driver are connected to the unit correctly. Solution 2Change the pulse output rotation direction of the parameters for each axis, and set it to thereverse direction.Point to checkCheck to make sure the CW/CCW output or the Pulse/Sign output is connected to thepertinent input of the servo amplifier and motor driver.
