Heidenhain · NC Control
The measured status of the 'RDY.x' signal remains active and fails to change to the 'inactive' ('low' level) status, even though the MC (Motion Control) is actively blocking the power module via a corresponding enabling signal. This indicates an internal software error or a hardware defect.
Click steps to track your progress.
Power cycle the NC control and the relevant power module(s) to reset all associated signals and states.
Check the cabling of the RDY.x signal and the enabling signal from the MC to the power module for integrity and proper connection.
Inspect the power module itself for any fault indicators, visible damage, or signs of component failure.
Verify the software configuration for the MC and power module regarding the RDY.x signal's expected behavior during blocking.
Use a multimeter to measure the RDY.x signal level to confirm if it remains active (high) when it should be inactive (low).
