1. Check whether the robot IP address and the third party settings are in the same network segment or whether there is any conflict in the IP address;

2. Click Menu-Communication-Bus Configuration-Configuration on the robot teach pendant to check whether the function is active or not, and the correct status should be active;

3. Click Menu-Communication-IO Mapping on the Teach Pendant, and enter the IO Mapping configuration page to confirm whether the module number is selected as “ModbusServer/TCP/128/256in:256out”;

4. Check whether the IO signal number and mapping start port number are correct.

1. Check whether  the PR bit pose registers used in the program have  been deleted or changed in ID number;

2. Check whether the DI, DO,GI and GO signals used in the program aremapped;

3. Check whether the SR, R, etc. registers used in the program are present.

Check the RCC cable

1. Check whether the RCC cable is damaged or exposed.

2. Check whether the cable between the robot and the RCC is loose.

3. Check whether the cable connection between the robot control cabinet and the RCC is loose;

4. Use a multimeter DC voltage file to measure whether the encoder battery of the robot body has voltage (about DC 3V);

5. Check whether the cable connecting to the encoder is damaged.

1. Use a multimeter AC to measure whether the robot power supply voltage meets the power supply requirements;

2. When operating the robot in manual mode, check whether the Deadman switch on the back of the Teach Pendant is in the middle gear and press the RESET button;

3. Check whether the connecting cable between the robot control cabinet and the body is broken。

Please calibrate the zero point according to the requirement first, then use the backup program to restore the point information, and finally teach the points.

1. Check the name plate of the robot control cabinet, confirm that the input and output signal type of the control cabinet is NPN or PNP, and confirm the wiring according to the requirements of the manual;

2. Check whether the output signal common terminal (COM) is wired correctly, and confirm whether the signal wiring pin port is correct;

3. Check whether the IO signal mapping is correct;

4. Check the signal meter to confirm that the robot output signal controls the relative components;

5. Check whether the control cabinet is effectively grounded.

1. Use a multimeter to measure whether the power supply voltage of the robot control cabinet complies with the rated voltage 220V;

2. Check whether the robot power supply plug is loose;

3. Check whether the external power supply wiring has a false connection or loose site;

4. Check whether the robot power supply cable specifications meet the requirements.

Please follow the steps below to check the contents of the program:

1.Check whether the subroutine called by the Call instruction exists and check whether the name is consistent (case-sensitive);

2.Check whether the subroutine run by Run instruction exists and check whether the name is consistent (case-sensitive);

3.Check whether the subroutine loaded by LOAD instruction exists and check whether the name is consistent (case-sensitive).
