How to Set Servo Motor Parameters for Beginners?

For practitioners debugging servo motors for the first time, the large number of parameters can be overwhelming. In fact, by tuning five core parameters first, you can achieve stable positioning operation of the servo motor and greatly lower the debugging difficulty.

1,Complete standard wiring before powering on the servo for commissioning. If the motor rotation direction is opposite to the control command during trial operation, there is no need to rewire the UVW phases. You can directly modify the rotation direction parameter inside the drive to quickly correct the direction, which is more convenient and safer.

2,Servo drives have three common control modes: position mode, speed mode and torque mode. Most units are factory-set to position mode by default. This mode fits most positioning requirements and is recommended for beginners. There is no need to try the more complex torque or speed modes at the start.

3,Under position mode, pulse signals sent from the PLC to the servo drive mainly fall into two types: pulse + direction, and double pulse. Pulse + direction is preferred for ordinary automation applications thanks to simpler wiring and programming, as well as wider compatibility.

4,Pulses per revolution is a critical parameter for positioning accuracy. It refers to the number of pulses required for the motor to complete one full rotation. This setting directly determines the actual travel distance of the motor and must be verified carefully during commissioning.

5,Acceleration and deceleration time affects the smoothness of motor operation. If this value is set too low, the motor tends to vibrate and generate abnormal noise when starting or stopping. A properly extended acceleration/deceleration time cushions impact and enables smoother start-stop action.

By mastering the above five parameter tuning tips, beginners can quickly finish basic servo commissioning and achieve reliable positioning. Based on this foundation, advanced parameters such as rigidity and filters can be further optimized according to working conditions to improve overall servo performance.
