The communication parameters must be consistent with the upper computer, otherwise a communication connection cannot be established.
After parameter configuration:
Conduct no-load testing (no-load operation), monitor parameters such as r0021/r0027/r0031, and confirm that the equipment is running normally;
Gradually load the load, observe whether the protection function is triggered, and verify the rationality of the parameters;
Record key parameters (such as motor data, communication address) for easy maintenance in the future.
Common risk avoidance:
Avoid modifying the rated parameters of the motor (p0304, etc.) during operation, which may cause instantaneous overload tripping;
Do not set p0290 (overload response) to 1 (trip directly without derating) unless there is no possibility of overload on the load;
Incorrect setting of analog input type (voltage/current) (p0756) can result in abnormal frequency setting.
