To adjust the Panasonic servo drive command position deviation, you can consider the following steps:
Check the mechanical system: First, ensure that the mechanical system has no faults or obstacles that hinder movement. Check transmission, bearings, couplings and other components to make sure they are working properly and not worn out.
Parameter Adjustment: The parameter setting screen of the Panasonic servo drive is displayed. Here, you can find the parameters related to the deviation of the instruction position. Common parameters may include position gain, velocity gain, and acceleration gain. Adjust these parameters appropriately according to your application requirements to reduce position bias.
Gain adjustment: Adjusting the position gain can affect the driver's response to the instruction position. Increasing position gain can improve the tracking accuracy of instruction position, but it may also lead to system instability. Therefore, when adjusting the gain, increase it gradually and observe the response of the system.
Filter Settings: Some Panasonic servo drives provide a filter function that reduces instruction position deviation. You can try enabling the filter and adjusting its parameters to see how it improves the position deviation.
Dynamic adjustment: Observe the change of position deviation when the servo system is running. If the deviation occurs under certain conditions, such as high-speed motion or during acceleration and deceleration, dynamic adjustments can be made for these conditions to optimize the performance of the system.
Software control: If your system allows, consider compensating for instruction position deviation at the software level. For example, you can write a program that monitors the position deviation in real time and compensates for the deviation by adjusting the instruction position.
Check for external interference: External interference, such as electromagnetic interference or vibration, may affect the performance of the servo system. Ensure that the drive and its surroundings are free from potential sources of interference and take necessary protective measures.
Note that the above steps provide only a general adjustment method. The specific adjustment method may vary depending on the model and application scenario of the Panasonic servo drive. Therefore, before making adjustments, it is recommended to refer to the Panasonic servo drive's user manual or contact technical support for more detailed and accurate guidance.
