All errors are latched. This means that even if the physical cause disappears, the controller remains in an error state until you issue an (via a rising edge on the DIN 3 input or via software).
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 |
: Issues with the Digital I/O interface or Ethernet connection. Diagnostic Memory
The is a compact motor controller used primarily for controlling stepper motors in automated systems. When this device encounters a problem, it displays error codes (typically as hex codes or through a 7-segment display) to help technicians diagnose issues ranging from simple wiring errors to critical hardware failures.
Short circuit or earth fault. Detected at the motor phases (A, A/, B, B/) or inside the motor cable casing. Ensure the motor is correctly initialized
Check the motor cable for breaks and ensure the encoder is properly connected. Verify that the holding brake is releasing correctly if one is integrated. Diagnostic Interface Overview
If the error persists after tuning, measure the motor cable resistance from the drive’s X2 connector to the motor. A common unnoticed failure is a broken shield drain wire causing EMI-induced step corruption at high microstepping (e.g., 1/256).
Ensure the power supply unit can handle the required current. 2. Error Group 02: Motor Overcurrent/Power Stage Failure (Short Circuit) / (Power Stage Overheat)
