Controller operating mode not allowed

¿Qué significa 4502 ?

The value specified for the controller operating mode is not allowed, as the value range is limited to [1]. An incorrect operating mode prevents the controller from initiating or maintaining its intended control function. This will effectively stop the controller from performing any motion or regulation tasks.

• Attempt to set the controller operating mode parameter (e.g., P3-03, Operating Mode) to a value other than '1' when only '1' (e.g., velocity mode) is allowed.
• The system's control architecture or application requires a specific operating mode, and a different, unsupported mode was selected.
• Programming error or configuration tool issue automatically defaulting the operating mode to an invalid or unallowed setting.
• Firmware limitation: The current controller firmware only supports a single operating mode, and any other selection is rejected.

1. 1

   1. Access the controller operating mode parameter (e.g., P3-03) and ensure it is explicitly set to '1' (or the single defined valid value).

2. 2

   2. Review the application's design specifications to confirm that '1' is the intended and required operating mode for the controller.

3. 3

   3. Check for any PLC or NC program blocks that might be attempting to dynamically change the operating mode to an invalid value.

4. 4

   4. Perform a parameter upload from the controller and verify that parameter P3-03 is indeed '1' before downloading a new configuration.

5. 5

   5. Consult the controller's manual to understand why the operating mode is limited to [1] and what this implies for application development.
