YoungYou company focus on :ABB Robot Maintenance Common Fault Questions and Answers

（1） What should be done if ABB robots enter a system fault state when starting up?

Answer:
1. Restart the robot once.
2.If not, check the teaching pendant for more detailed alarm prompts and take action.
3. Restart.
4. If it still cannot be released, try B startup.
5. If it still doesn't work, please try P startup.
6. If it still doesn't work, please try I startup (this will return the robot to its factory settings, be careful).

（2） Under what circumstances does it need to be backed up for robots?

Answer:
1.After the new machine is first powered on.
2.Before making any modifications.
3. After completing the modifications.
4. If the robot is important, it should be done once a week on a regular basis.
5. It is best to make a backup on the USB drive as well.
6. Regularly delete old backups to free up hard drive space.

（3） Can robot backup be shared by multiple robots?

Answer:
No, for example, the backup of robot A can only be used for robot A, not for robot B or C, as this can cause system failures.

（4） What files can be shared in robot backup?

Answer:

If two robots are of the same model and configuration. You can share the RAPID program and EIO file, but after sharing, it also needs to be verified before it can be used normally.

（5） What is the meaning of the 10106 maintenance time reminder when the robot displays an alarm message?

Answer:

This is an ABB robot intelligent periodic maintenance reminder.

（6） What is the mechanical origin of robots? Where is the mechanical origin?

Answer:

Each of the six servo motors of the robot has a fixed mechanical origin. Setting the robot's mechanical origin incorrectly will cause problems such as limited or incorrect movement of the robot, inability to walk in a straight line, and in severe cases, damage to the robot.

（7） How to clear the action monitoring alarm of robot 50204?

Answer:
1. Modify the robot action monitoring parameters (in the control panel action monitoring menu) to match the actual situation.
2. Use the AccSet command to reduce the robot's acceleration.
3. Reduce v in speed data_ The rot option.

（8） What to do with the alarm "50296, SMB memory data difference" when the robot is powered on for the first time?

Answer:
1. Select Calibration from the ABB main menu.
2. Click on ROB_ 1. Enter the calibration screen and select SMB memory.
3. Select "Advanced", enter and click "Clear Control Cabinet Memory".
4. After completing, click "Close" and then click "Update".
5. Select 'Swapped control cabinet or robotic arm, updating control cabinet with SMB memory data'.

（9） How to customize the speed of robot trajectory motion in the RAPID program?

Answer:
1. Select Program Data from the main menu of the teaching pendant.
2. After finding the data type Speeddata, click New.
3. Click on the initial value, and the meanings of the four variables Speeddata are: v_ TCP represents the linear running speed of the robot, v_ Rot represents the rotational speed of the robot, v_ Leax represents the linear operating speed of the external axis, v_ Reax represents the rotational speed of the external axis. If there is no external axis, the last two do not need to be modified.
4. The customized data can be called in the RAPID program.

Routine maintenance methods for ABB industrial robots:
1. Brake inspection
Before normal operation, it is necessary to check the motor brake on each axis. The inspection method for the motor brake is as follows:
(1) Run the axis of each robotic arm to its high load position.
(2) Turn the motor mode selection switch on the robot controller to the MOTORS OFF position.
(3) Check if the shaft is in its original position. If the mechanical arm still maintains its position after the motor is turned off, it indicates that the brake is in good condition.

2. Danger of losing deceleration operation (250mm/s) function
Do not change the gear ratio or other motion parameters from the computer or teaching pendant. This will affect the deceleration operation (250mm/s) function.

3. Safe use of teaching aids
The enabling device button installed on the teaching pendant, when pressed halfway, changes the system to MOTORS ON mode. When the button is released or fully pressed, the system changes to MOTORS OFF mode.
In order to use the teaching pendant safely, the following principles must be followed: the Enabling device button must not lose its function. When programming or debugging, when the robot does not need to move, immediately release the Enabling device button.
When programmers enter a safe area, they must always carry the teaching pendant on their body to prevent others from moving the robot.

4. Working within the working range of the robotic arm
If it is necessary to work within the working range of the robotic arm, the following points must be observed:
(1) The mode selection switch on the controller must be turned to the manual position in order to operate the enabling device to disconnect the computer or remotely operate;
(2) When the mode selection switch is in the<250mm/s position, the maximum speed is limited to 250mm/s. When entering the work area, the switch is generally set to this position. Only those who are very familiar with robots can use full speed (100% full speed);
(3) Pay attention to the rotation axis of the robotic arm, be careful when hair or clothing gets mixed up. Also, pay attention to other selected components or equipment on the robotic arm;
(4) Check the motor brake for each axis.
