The controller cannot read the encoder signals on [X2], or the actual position deviates too much from the target position. Troubleshooting:

These codes point to physical blockages or communication dropouts between the motor feedback loop and the controller.

Power cycle the logic supply. If the fault persists, use the Festo Configuration Tool (FCT) to clear the internal memory and upload a fresh parameter set or re-flash the firmware. 2. Power Supply and Voltage Monitoring (Group 02)

| Error Code | Name | Description | Immediate Action | | :--- | :--- | :--- | :--- | | | Driver Overtemp | Internal heat sink > 85°C | Improve airflow; reduce duty cycle; check ambient temperature. | | 0x2200 | Motor I²t Overload | RMS current limit exceeded (object 0x2030h) | Increase cycle time; reduce load inertia; enable standstill current reduction. | | 0x2300 | Sensor Temperature | NTC sensor on PCB reports > 90°C | Clean ventilation slots; verify mounting orientation (vertical recommended). |

The controller or motor has exceeded its safe operating temperature.

Each code triggers a specific internal action, ranging from a harmless warning (where the motor keeps running) to severe system faults that instantly cut power via the safety function. Common Error Codes Reference Table CMMO-ST-C5-1-DIOP/DION - Festo

Here are the top 5 errors reported by techs working on systems with this controller: The controller cannot read the encoder signals on

It looks like you’re trying to make sense of an error code related to a — which is a Festo stepper motor controller (part of the CMMO-ST series for stepper motors with integrated I/O and IO-Link).

Here is the master table of codes you will encounter. Note that when we refer to "blink codes," count the number of short flashes, followed by a long pause.

: Indicates a Fault (Error). These have the highest priority and must be acknowledged before operation can resume.

Indicates the function has been requested or is active. Operational Status Pxxx If the fault persists, use the Festo Configuration

Error and status messages on the CMMO-ST follow a specific hexadecimal format on the 7-segment display. Message Type Priority & Behavior Exxx

The is a stepper motor controller featuring a digital I/O interface and the Safe Torque Off (STO) safety function. Diagnostic messages on this device are primarily displayed through its integrated 7-segment display or can be accessed via the Festo Configuration Tool (FCT) software. Overview of Diagnostic Codes
