تحري الخلل وإصلاحه

If you encounter issues, consider the following general troubleshooting steps:

• لا يوجد طاقة: التحقق من حجم الإدخالtage and ensure all power connections are secure. Check for blown fuses if applicable.
• المحرك لا يتحرك: Confirm control signals (PUL, DIR, EN) are correctly wired and active. Check motor wiring for correct phase connections. Verify current and subdivision settings are appropriate for your motor.
• ارتفاع درجة الحرارة: Ensure the driver has sufficient airflow. Check if the motor current setting is too high for the application.
• مؤشر الإنذار: If the alarm indicator is active, check for overvoltagه ، undervoltage, phase current overcurrent, or motor phase open circuit conditions as described in the product overview.

For persistent issues, refer to the detailed wiring diagrams and configuration tables, or contact CNCTOPBAOS technical support.
