If you can tell me (steady red, flashing how many times, repeating pattern) or an error code you saw in IO-Link software , I can give you the precise meaning and fix.
: Specific documentation for errors related to the Safe Torque Off (STO) safety function. Motor controllers CMMO-ST - Festo Didactic Infoportal
Errors range from recoverable warnings (e.g., temperature threshold alerts) to fatal faults (e.g., short circuits requiring power cycling).
: Errors are usually categorized by their reaction (e.g., B, C, D, E, F, G ) and whether they are immediately resettable via the CCON.RESET bit. Common Diagnostic Examples
Blink codes are essential for field troubleshooting, but for precise diagnostics, you need the (FCT) software. Connect via USB (Micro-USB port on the front).
(Over-temperature) is common if the controller is mounted in a tight space without airflow. 2. Connect via FCT (Festo Configuration Tool)
