Troubleshooting
8.2.3 Motor Does Not Rotate/Move (Output LED Flashes or is ON)
Solution 1: For servo motor
Check to make sure the servo on input is set to "ON".
Solution 2
Check to make sure the power supplies for the servo amplifier and motor driver are ON.
Solution 3
Check to make sure the servo amplifier and motor driver are connected to the unit correctly.
Solution 4
Check to make sure the settings for the pulse output method (CW/CCW method or Pulse/Sign
method) are appropriate.
8.2.4 Motor Does Not Rotate/Move (Output LED is OFF)
Solution
Review 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 1
Check to make sure the servo amplifier and motor driver are connected to the unit correctly.
Solution 2
Change the pulse output rotation direction of the parameters for each axis, and set it to the
reverse direction.
Point to check
Check to make sure the CW/CCW output or the Pulse/Sign output is connected to the
pertinent input of the servo amplifier and motor driver.
