Error Codes [2021] - Cmmo-st-c5-1-diop
Always consult the official Festo CMMO-ST Manual for a complete list of hexadecimal error codes and parameter recovery procedures.
The CMMO-ST-C5-1-DIOP employs a three-tier classification system for diagnostic messages. These classifications can be parameterized using the Festo Configuration Tool (FCT).
| 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). | cmmo-st-c5-1-diop error codes
Hardware-level protection mechanisms trigger these codes to prevent catastrophic component melting or winding degradation.
When a fault occurs, the display flashes an active sequence containing an followed by a 4-digit diagnostic code . This code is broken down into an Error Group (first two digits) and an Error Number (last two digits). Example Sequence: If the display flashes E →right arrow 0 1 →right arrow Always consult the official Festo CMMO-ST Manual for
: Regenerative energy from a decelerating motor has pushed voltage too high. Consider installing an external braking resistor. Group 02: Overtemperature and Thermal Monitoring
Festo group categories classify each diagnostic code to trigger a specific, programmable error response: | Error Code | Name | Description |
The controller monitors both its and the load voltage feeding the motor H-bridge power stage.
