Connect the controller via the Ethernet interface to view detailed error descriptions and time-stamped logs in the Festo Configuration Tool.

Errors are categorized based on their cause and severity. Key monitored parameters include: Hardware/Power Faults

The 7-segment display on the front of the unit cycles through four characters to indicate current status, errors, or warnings:

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). cmmo-st-c5-1-diop error codes

: Free-wheeling power stage. The motor drops all torque immediately.

Cause : The deviation between the calculated setpoint position and the actual feedback value exceeds the parameter threshold configured in the Festo Configuration Tool (FCT).

: Interrupted Modbus TCP connections or IO-Link/DIOP interface failures. Frequently Encountered Codes Connect the controller via the Ethernet interface to

The CMMO-ST's primary communication tool is its 4-character 7-segment display. All messages—operating modes, errors, and warnings—are displayed here. The diagnostic messages for errors or warnings are displayed as a 4-character code in (shown after a leading E or A ). For example, E 33h on the display corresponds to a specific error code.

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. : Free-wheeling power stage

: Toggle the CCON.RESET bit via your master controller, or click "Acknowledge Error" inside the FCT environment to resume operations. Summary Table: Quick Reference CMMO-ST-C5-1-DIOP/DION - Festo

Adjust your position window and acceptable following error tolerances in the FCT parameterization menu.

Ensure your ambient enclosure temperature falls within the required 0 to 50 °C range and that the controller's sub-base is mounted with specified cooling clearances. For motor errors, confirm the axis is not mechanically jammed or working against a heavy load. 4. Motion Control and Following Errors (Group 06)
