Messages on the display follow a specific pattern to help you quickly identify the type of information being shown. Diagnostic messages for errors or warnings are coded in hexadecimal format. Key prefixes indicate the following:
: Displayed as - x x y - , where the dashes replace the "E" to distinguish them from critical errors. Common CMMO-ST Error Categories
The integrated display has space limitations, so it cycles through , followed by a brief blank space, to flash active diagnostics.
The 7-segment display on the front of the unit provides immediate visual feedback. Error messages typically consist of a sequence of characters starting with an (Error) or "W" (Warning), followed by a code. Common Error and Warning Categories
Error 0x47 often indicates a lost connection with the master control. Improper safety circuit wiring cmmo-st-c5-1-diop error codes
Leave at least 10mm of free space on both sides of the CMMO-ST housing inside the enclosure to facilitate natural convection.
. In the world of industrial automation, these controllers are the "brains" that tell robotic actuators exactly where to move. However, like any brain,
When a fault occurs, the motor controller enters an error status, and the error must be managed appropriately.
: A single flashing point typically indicates the bootloader is active or firmware is being read from a memory card. Error Codes : These are displayed in the format E x x y . E : Signifies an error. xx : The two-digit main index of the error. y : The single-digit sub-index. Messages on the display follow a specific pattern
: Sometimes, errors are due to software or firmware issues. Check if there are any updates available.
The motor is not in the position it is supposed to be in.
Ensure the Safe Torque Off inputs at [X3] are correctly powered (24V).
Keep this guide printed inside your control cabinet door. When those LEDs start blinking, you’ll know exactly what action to take. Common CMMO-ST Error Categories The integrated display has
Based on the nomenclature , this guide pertains to the Festo CMMO-ST (Controller for Motorized Motion – Servo/Stepper Technology) series, specifically a model equipped with an integrated Digital I/O (DIOP) option.
Power stages deactivate or execution stops based on the configuration. The error can be cleared via digital inputs (CCON.RESET) or software command once corrected.
The integrated Safe Torque Off (STO) subsystem relies on dual-channel control logic.
