5.2. Initial Parameter Setting Guide
To ensure optimal performance and compatibility with your motor, follow these steps for initial parameter setup. This guide focuses on common settings for 50Hz parameters.
- коюу pn32 (Parameter management) = 6 (initialization for 50Hz parameters).
- коюу pn02 (Initial start up frequency by panel or other external signal) = Load rating frequency.
- коюу pn03 (Source of runtime frequency) = 2 (Panel button).
- коюу pn04 (Source of runtime command) = 1 (Panel button control).
- коюу pn10 (Maximum runtime frequency) = Load rating frequency.
- коюу pn12 (Motor rating frequency) = Load rating frequency.
Note: For 60Hz parameters, adjust relevant frequency settings accordingly. Consult the full manual for detailed parameter descriptions (Chapters 5-7).
