Setpoint generator is inactive

What does 4227 mean?

The setpoint generator, responsible for calculating and outputting motion commands, is currently inactive. This means the system cannot accept any new motion instructions, as the core mechanism for generating movement is not operational. This can occur if the NC is not in a ready state or requires an explicit activation command.

• NC controller is not in an operational or 'Ready' state (e.g., in reset, booting, or experiencing a critical fault).
• Main NC system enable signal (e.g., 'NC_System_Enable' bit from PLC) is not active.
• A critical internal NC error (e.g., 4000 Internal Error, 4001 Memory Error) has caused the setpoint generator to halt.
• No active NC program or motion task is loaded/running that would activate the generator's calculation engine.
• Setpoint generator module has been explicitly disabled through configuration (e.g., P1-05 'SGenEnabled' set to FALSE).

Click steps to track your progress.

1. 1

   1. Check the overall status of the NC controller to ensure it is in a 'Ready' or 'Operational' state, not faulted or in reset.

2. 2

   2. Verify the main system enable signal (e.g., 'NC_System_Enable' bit in PlcToNc interface) is active from the PLC.

3. 3

   3. Address and clear any other active NC fault codes (e.g., 4000, 4001) that might be preventing the setpoint generator from starting.

4. 4

   4. Ensure an NC program (e.g., G-code file) is loaded and running, or a motion command is being actively issued.

5. 5

   5. Check configuration parameter P1-05 ('SetpointGeneratorEnabled') and ensure it is set to TRUE.

6. 6

   6. Perform a full power cycle of the NC controller to reset its internal state and reinitialize components.
