12-4 Troubleshooting Symptom Vibration is occurring at the same frequency as the power supply. The position is misaligned. (Position misalignment occurs without an error being output.) Probable cause Inductive noise is occurring. Items to check Measures Shorten the control signal lines. Check to see if the control signal lines and power supply lines are bound together. • Separate control signal lines from power supply lines. • Use a low-impedance power supply for control signals. There is an error in the Check to see if the coupling of coupling of the mechanical the mechanical system and system and the Servomotor. the Servomotor is misaligned. Correct the coupling between the mechanical system and the Servomotor. The gain is wrong. − Check if manual tuning can achieve proper adjustment. The load inertia is too large. • Check the load inertia. • Check the Servomotor rotation speed. • The dynamic brake resistance is disconnected. • Review the load inertia. • Replace the Servomotor and Servo Drive with proper ones. OMNUC G5-series AC Servomotors and Servo Drives User’s Manual (with Built-in EtherCAT Communications) 12-30 12 Troubleshooting and Maintenance Check to see if the drive control signal lines are too long.
