Does the DSY-RS Series Servo Motor Have Specific Commands or Function Codes to Interrupt or Prevent Writing After Correct Parameter Configur

To achieve correct servo parameter configuration and prevent runtime alarms, the core approach involves managing parameter writes through the controller (e.g., a PLC). There are two main methods:

One-Time Write, Effective on Power-On

Map the data addresses of the servo parameters that need to be set to the controller's startup parameter area once. This way, when the equipment powers on, the controller automatically writes these parameters to the servo driver. This method ensures parameters are written only once during initialization, perfectly avoiding the restriction of inability to modify parameters during motor operation. It is suitable for basic configurations that do not require frequent changes.

Runtime Modification, Safe and Controlled

If a specific parameter needs individual adjustment during production, it can be modified via the PLC program or HMI controls through 485 communication (or other fieldbus).

The key point is that the PLC program logic must determine whether the current state is safe (e.g., the motor has stopped) before executing the write operation. This approach both meets the need for flexible adjustment and fundamentally prevents alarms triggered by improper writes.

Summary: Through proper planning in the controller, parameters can either be solidified once or safely and flexibly modified online when needed. This ensures stable operation of the servo system and avoids alarms.
