Most errors (marked Exxx ) require an acknowledgment signal via the digital I/O interface or the software before the drive can be re-enabled.
. These codes typically appear as "E" followed by a three-digit hex value (e.g., 🛠️ Decoding the Error Display The 7-segment display cycles through the error information: First digit of the hex code Second digit of the hex code Third digit of the hex code 📋 Common Error Codes & Solutions Power & Voltage (0x02, 0x03) Probable Cause Undervoltage Logic or load voltage is below 18V. Check 24V power supply and wiring. Overvoltage Braking energy too high or supply > 30V. Reduce speed/load or check supply. Motor & Temperature (0x11, 0x12) Probable Cause Over-temperature Device or motor is too hot. Check ambient temp and duty cycle. I²t Error Continuous current too high for too long. Check for mechanical jams or friction. Motion & Feedback (0x17, 0x24) Probable Cause Following Error Position lag is too large. Increase current or reduce acceleration. Encoder Error Signal loss or cable breakage. Check [X2] connector and encoder cable. Safety (0x1E) Probable Cause Safe Torque Off state is inconsistent. Check [X3] wiring and safety relay. 🔍 Diagnostic Workflow cmmo-st-c5-1-diop error codes
