(Over-temperature) is common if the controller is mounted in a tight space without airflow. 2. Connect via FCT (Festo Configuration Tool)

) power inputs. Check for voltage sags when the motor accelerates.

The controller communicates errors via an explicit code layout ( Exxx or a raw hexadecimal string). The table below lists the most common error groups encountered during commissioning and operation: Error / Code Range Common Cause Recommended Action (Bootloader Error) Failed firmware update or corrupted memory flash.

: Severe firmware download interruption.

To minimize the frequency of these errors, adhere to the following installation standards: cmmo-st-c5-1-diop error codes

[Error Code Triggered] │ ├──► Check Power: Is Load/Logic Voltage stable under load? │ ├──► Inspect Wiring: Are Encoder & Motor lines shielded? │ └──► Verify Software: Do FCT parameters match physical limits? Power Infrastructure Verification

Homing error. The controller failed to find the reference switch or index pulse within the specified maximum search path.

Following error (Tracking error). The deviation between the target position and the actual position exceeds the configured tolerance window.

High priority. Interrupts lower-priority messages and to resume operation. Warning Axxx (Over-temperature) is common if the controller is mounted

: A short circuit was detected in the motor cables or motor windings. Inspect the cabling at [X6] for damage.

: If the error relates to a specific process parameter (like temperature, pressure, etc.), verify that these parameters are within the required ranges.

) to access the most current technical descriptions and error lists. Verify STO Logic:

While a full list of specific hexadecimal codes is typically detailed in the Product and Functional Description Manual (GDCP-CMMO-ST-EA-SY) , they generally fall into these protective functional categories: I2tcap I squared t Check for voltage sags when the motor accelerates

Disconnect the motor cable and check resistance across phases. Winding resistance must match Festo motor specifications exactly. Any reading to the cable shield indicates a ruptured cable. Software Calibration via Festo Configuration Tool (FCT)

When STO is active (requested on two channels), the power stage is switched off on both channels, the motor cannot be operated, and the STO function is active. The diagnostic message 0x34 (Safe Torque Off) is generated and can be displayed on the 7-segment display. Acknowledgment of STO is handled by the safety circuit.

Errors related to the Safe Torque Off (STO) function, such as channel discrepancies (e.g., if one STO channel is high and the other is low for too long).
