Heidenhain · NC Control
An error has occurred in the Digital Signal Processor (DSP) within the power stage of the displayed axis. This indicates a critical fault in the axis drive's control electronics.
Click steps to track your progress.
Power cycle the NC control and the affected axis drive to clear any transient errors and reset the system.
Inspect the power wiring and feedback connections between the drive, motor, and NC control for the specified axis for any damage, loose terminals, or poor shielding.
Check for any external mechanical issues, such as binding or collisions, that might have caused an overload condition in the power stage.
Verify the motor encoder feedback and its cabling, as incorrect or intermittent feedback can lead to power stage instability.
If the error persists after these checks, consider documenting all relevant machine and program data for review by a service agency.
