EA180 Series Servo Drive Users Manual 101 Al00D / Al00E : Motor overload/drive overload Alarm Scenarios Inspection Troubleshooting Continuous use in excess of rated load 1: Monitor whether d0-01 continues to exceed 100% 2: Monitor whether d0-46 continues to exceed the rated value 3: Monitor whether d0-47 ~ 49 continues to increase 1: Increase motor capacity or reduce load 2: Increase drive capacity or reduce load Wiring error of motor and encoder Check U, V, W and encoder wiring Ensure correct wiring The power line of the motor is broken or has poor contact. 1: Check whether the motor power line is connected to the drive reliably 2:
Check whether the connection between the power line and the motor is reliable, especially for the ones using plastic connectors. 1: Fasten the screws to eliminate problems such as poor contact and poor cable crimping. 2: Fix the connections so that they will not shake or be subjected to external pulling force. 3. Check whether the reeds in the plug are deformed or not and correct it. Improper setting of control parameters 1: Whether the machine oscillates and whether the motor makes abnormal noise 2: The acceleration and deceleration is set too rapid 1: Adjust position and speed gain value 2:
Decrease the acc/dec time Drive or motor fault Remove the above faults Send it to distributor or manufacturer for overhaul. Al010 : Drive overheating Alarm Scenarios Inspection Troubleshooting High ambient temperature Check whether the ambient temperature and humidity are within the allowable range Improve installation environment Drive cooling fan is damaged Check whether the cooling fan is running during operation Replace the fan that does not work The heat dissipation of the servo drive is affected 1: Check whether the drive installation meets the requirements 2: Check whether the radiator of the drive is blocked 1: Install the drive correctly according to the requirements of Chapter 2 2:
Clean up the blockage Al012 : Overspeed Alarm Scenarios Inspection Troubleshooting UVW phase sequence error Check if the UVW phase sequence is correct Do wiring according to correct phase sequence Improper setting of over-speed judgment parameters Check whether the over-speed parameter is set too small Correctly set the over-speed parameter The speed input command has changed dramatically. Check whether the input analog voltage signal is abnormal Adjust the change rate of the input signal or adjust the filtering The encoder is disturbed Whether the wiring layout is appropriate and whether the system is grounded Adjust the wiring layout and ensure reliable grounding of the system Al013 :
Position deviation is too large Alarm Scenarios Inspection Troubleshooting Position following error alarm value is too small Confirm whether P1-20 parameter is appropriate Increase the set value of P1-20 The pulse command frequency is higher than the specification. Detect the pulse command frequency Adjust the pulse frequency to be lower than the specification. Gain value is set too small Check if the set value is appropriate Set the gain value correctly
