6.1.20.2. Causes and examine methods​

 

(1)    Please examine if the Main Board and the Servo Board are installed properly.

n  Examine if the board is installed properly.

n  Examine if board is faulty.

 

(2)    Examine if there is a job program that operates a Robot rapidly.

 

(1)   Please examine if the Main Board and the Servo Board are installed properly.

This error may be caused by a communication problem if the Main Board and the Servo Board is not installed properly on a rack, or the board has an error.

 

Warning

In order to protect the previous job programs, please back up all the files of Main board to the USB memory before you remove the board from the Rack.

 

Method to back up the files from Main Board to USB memory is as below.

 

 

Figure 1.98 Methods for inserting a USB into the teach pendant

 

Once the USB is recognized by TP, the below icon will be displayed on a screen.

 

 

To back up the files enter to

 

Ø Service

Ø 5. File manager

 

And the screen that is similar to windows explorer will be displayed.

 

 

At this stage, please copy the files shown in M/B and move them to USB.

 

 

 

You may create a new folder on USB, or can rename the folder by using the soft keyboard just like the windows explorer.

 

 

 

 

n  Examine if the board is installed properly.

Please remove the Main Board and the Servo Board from the Rack and re-install them again.

n Examine if the board is faulty.

To examine if the board is faulty, please replace it with new one.

 

(2)   Examine if there is a job program that operates a Robot rapidly

Please check if the error occurs at a point where the Robot’s motion changes rapidly. If the error occurs during the rapid motion, modification of job program is required.

 

The reason that this error occurs during the rapid motion is as below. During the execution of job program, Robot’s position may be twisted in order to move a short distance. At that point, the speed of Robot’s axis suddenly increases, and the error may occur if the Servo Board follows the movement. In order to resolve this, please modify the Teaching point of the location (where the position changes rapidly) or make changes on the position of Robot.
