Troubleshooting of Servo Drive and its Precaution

Servo drive is an indispensable and important component of modern industrial automation system, and its normal operation has an important impact on the stability and productivity of the production line and production efficiency has an important impact. However, due to a variety of factors, the servo drive may appear a variety of failures. In order to ensure the stable operation of the servo drive, we need to take a series of measures to prevent and solve the problem. In this article, we will discuss the common servo drive failures, how to prevent and solve servo drive failures and other topics.

Common faults

Fault phenomenon: servo motor can not start
  •     Check whether the power supply is normal, whether the cable connection is firm.
  •     Check whether the servo motor is overloaded, if necessary, reduce the load.
  •     Check whether the servo drive is working properly, if any failure, need to be replaced.
Fault phenomenon: servo motor running during the sudden stop
  •     Check whether the servo motor is overloaded, such as overload, need to reduce the load.
  •     Check the heat dissipation of the servo drive, if necessary, need to strengthen the heat dissipation.
  •     Check whether the power supply voltage is stable, if necessary, need to add voltage regulator.Servo drive
Fault phenomenon: servo motor positioning is not allowed
  •     Check whether the encoder is normal, such as failure, need to be replaced in a timely manner.Servo drive
  •     Check whether the parameter setting of servo driver is correct, including gain, integration time, etc.
  •     Check whether the mechanical part is loose, if necessary, need to fasten the parts in time.
Failure phenomenon: servo motor running in the process of noise
  •     Check whether the installation of servo motor and mechanical parts is normal.
  •     Check whether the bearing inside the motor is damaged, if necessary, need to replace the bearing.
  •     Check whether there is foreign matter inside the motor, if necessary, need to clean up.
Fault phenomenon: servo motor overheating
  •     Check whether the heat dissipation of the servo motor is good, if there is any problem, need to strengthen the heat dissipation.
  •     Check whether the power supply power is sufficient, if the power supply power is insufficient may lead to motor overheating.
Preventive measures

Keep the equipment clean

The cleanliness of the equipment is vital to the normal using of the servo drive. Dust, dirt and other impurities may intrude into the device's interior, affecting its thermal performance and and affect its thermal and electrical performance, leading to malfunctions. Therefore, keeping the equipment clean is an important measure to prevent Servo Drive failures.

Therefore, keeping the equipment clean is an important measure to prevent servo drive failures. Operators should regularly clean the surfaces of the equipment and ensure the cleanliness of the environment in which the equipment is located.

Regular Inspection and Maintenance

Regular inspection and maintenance is an important means of preventing servo drive failures. Through regular inspection, potential problems and hidden dangers can be found in time, and action can be taken and hidden trouble, and take appropriate measures to repair and replace. Inspection should include electrical performance, mechanical performance, heat dissipation performance, and in accordance with the maintenance requirements of the equipment to carry out the corresponding maintenance and maintenance.

Implementation of fault diagnosis

Implementation of fault diagnosis is a key step in solving servo drive failure. Through fault diagnosis, you can quickly locate the cause of the failure, and provide maintenance personnel with clear maintenance guidelines. Troubleshooting methods include electrical testing, mechanical testing, parameter analysis, etc., the operator should be based on the actual situation, the operator should choose the appropriate method for diagnosis according to the actual situation.
