B&R Servo Drive Overheat Alarm Repair Quick Fixes

In order to keep industrial production running continuously, it is critical to find and fix B&R servo drive overheating alarms in a timely manner.

1 Check the power supply line: Use a multimeter to measure the power supply voltage to ensure that it is within the set value. If the power supply voltage is lower

1. Cause analysis

1.1 High ambient temperature: When B&R servo drive works in a high temperature environment for a long time, its internal temperature will continue to rise beyond the normal working temperature range, thus triggering the overheating alarm.

1.2 Overload work: If the load driven by B&R servo drive exceeds its carrying capacity, the load current will exceed the rated current, resulting in servo drive overheating.

1.3 Cooling system failure: B&R servo drive needs an effective cooling system in normal operation, if the cooling system fails, unable to dissipate heat in time, it will trigger overheating problems.

2. Repair method

2.1 Switch off the unit and allow it to cool down

2.2 Clean the cooling system

2.3 Check the load status and reduce the load

2.4 Check the supply voltage and power cables

2.5 Check fan operation and replace faulty fan

2.6 Replace the thermal protection device

3. Preventive measures

Ambient temperature control: ensure that the temperature of the B&R servo drive's working environment does not exceed the specified range, and measures such as air-conditioning refrigeration can be taken.

Regular Cleaning: Clean the B&R servo drive regularly, keep the cooling system unobstructed, and avoid blockage by dust and debris.

Load control: Reasonable control of the load to ensure that the load current does not exceed the rated current of the B&R servo drive.

Fan Maintenance: Check the servo drive fan operation regularly, and replace it in time if it fails.

Through the above analysis, we understand the causes of B&R servo drive overheating alarm, repair methods and preventive measures.
