Common faults and solutions of ABB spraying robot arm

ABB spraying robot arm motor temperature high (alarm "20252"):

Fault phenomenon: The motor temperature is too high, causing the alarm "20252".

Solution: First, check if the motor is overheated. If the motor temperature is normal, check if the connecting cables are functioning properly. It may be due to the aviation plug at the control cabinet not being properly plugged in. If the problem persists, the alarm signal can be temporarily short circuited, but it should be noted that doing so may cause the motor to fail to sound an alarm when it is truly overheated, posing a risk of burnout. Specific operation method: Find the A43 board in the lower left corner of the control cabinet, locate the 5 plugs on the board, and the two wires with wire numbers 439 and 440 are the motor overheating alarm signal wires. Disconnect and short-circuit these two wires from the middle

ABB spraying robot arm power module short circuit board short circuit：

Reason for malfunction: Human factors such as hot swappable hardware, environmental factors such as dust accumulation, and other factors such as static electricity.

Solution: Regularly maintain and clean the circuit board, avoid hot swapping hardware operations, pay attention to the ventilation and dust prevention of the robot

Improper setting of drive control parameters:

Fault symptoms: uneven spraying, deviation in motion trajectory, etc.

Solution: Adjust the control parameters of the ABB robotic arm driver according to the actual situation, such as spraying speed, acceleration, spraying distance, etc., and ensure the preservation and backup of the parameters

‌Common faults and solutions of ABB spraying robot arm

ABB spraying robot arm driver power failure：

Fault phenomenon: The drive cannot start or works unstably.

Solution: Check if the power cord connection is secure and use a multimeter to check if the power voltage is stable. If the power module is damaged, it needs to be replaced with a new power module and the power parameters need to be readjusted

ABB spraying robot arm driver overheating fault：

Fault phenomenon: The driver generates a large amount of heat during operation, causing overheating.

Solution: Check if the cooling fan is running properly and clean the radiator to ensure good heat dissipation. If the cooling fan is damaged, a new fan needs to be replaced; If the radiator is severely clogged, a new radiator may need to be replaced
