As the core control component of automation equipment, the installation quality of servo drives directly determines the stability and service life of equipment operation. In actual installation, many overlooked details often become hidden dangers of faults, requiring rational analysis to accurately avoid various minefields and ensure efficient system operation.
Pre installation planning is prone to stepping into the "insufficient environmental adaptation" minefield. Some scenarios only focus on whether the installation space is sufficient, ignoring key factors such as environmental temperature and humidity, dust, and vibration. Servo drives generate heat during operation, and if installed in enclosed spaces or near heat sources, it can easily cause frequent triggering of overheating protection; A humid and dusty environment may cause internal circuit short circuits. The key points to avoid are to confirm in advance that the installation environment meets the requirements of the equipment manual, reserve reasonable heat dissipation gaps, equip cooling fans or dust covers if necessary, stay away from machine vibration sources and strong electromagnetic radiation equipment, and reduce the impact of the environment on the equipment from the source.
The "fixed and coaxial deviation" in the mechanical installation process is a high-frequency minefield. If there is a coaxiality error in the connection between the driver and the motor, or if the fixing bolts are not tightened to the specified torque, it may cause abnormal noise and vibration during operation, which may damage the bearings and couplings in the long run. During installation, it is necessary to use tools such as a dial gauge to calibrate the coaxiality and ensure that the deviation is within the allowable range; Bolt tightening follows the principle of uniform diagonal tightening to avoid uneven local stress, and anti loosening treatment is also done to prevent loosening during long-term operation.
The lack of standardization in wiring operations is an important cause of faults. Common problems include wiring errors, loose terminal crimping, improper handling of shielding layers, etc. Before wiring, carefully check the pin definitions and distinguish between power and signal lines to avoid module burnout caused by reverse connection; Terminal crimping should ensure that the wire is in full contact with the terminal without looseness or virtual connection; The shielding layer of the signal line needs to be grounded at one end to reduce the impact of electromagnetic interference on signal transmission, avoid parallel laying with the power line, and prevent signal crosstalk.
During the debugging phase, it is easy to fall into the minefield of "blind parameter settings". Some installation personnel did not consider the load characteristics and operational requirements of the equipment, and directly used default parameters or copied other equipment parameters, which may lead to slow response, insufficient positioning accuracy, and even overload and overcurrent alarms in the servo system. During debugging, a no-load trial run should be conducted first to gradually optimize key parameters such as position loop and speed loop gain. Parameter values should be adjusted based on actual operating conditions to ensure smooth system operation and accurate positioning. At the same time, parameter backups should be made for subsequent troubleshooting and recovery.
The installation of servo drives should adhere to the principle of "detail control and standardized operation" to avoid the key pitfalls mentioned above. Strictly following the requirements of the equipment manual during the installation process, taking into account environmental adaptation, mechanical accuracy, wiring specifications, and parameter optimization, can greatly reduce the risk of failure and ensure the long-term stable operation of the automation system.
