EA180 Series Servo Drive Users Manual Al00C : Software overcurrent See the description for Al002 100 Al007: Encoder exception 1 Alarm Scenarios Inspection Troubleshooting Encoder loose Check CN5 and encoder connector on drive Reinstall Encoder wiring error Check if the wiring of the encoder follows the recommended wiring in the instructions Ensure correct wiring Poor encoder wiring Check whether the connection between CN5 on the drive and servo motor encoder is good, including whether the shielding layer is in good condition. Do rewiring Encoder is damaged This alarm still occurs after wiring problems are eliminated Replace motor Al008 :
Encoder exception 2 Alarm Scenarios Inspection Troubleshooting Incremental encoder AB signal exception Same as Al007 Same as Al007 Absolute encoder CRC check error Al009 : Encoder Exception 3 Alarm Scenarios Inspection Troubleshooting Incremental encoder Z signal exception Same as Al007 Same as Al007 Absolute encoder communication error Al00A :
Undervoltage Alarm Scenarios Inspection Troubleshooting Input voltage of main circuit is lower than the allowable value Check whether the input voltage and wiring of the main circuit are normal Reconfirm power wiring No input voltage in main circuit Check whether the main circuit voltage is normal Reconfirm power switch Power error Check whether the power supply conforms to the specification required Use the correct power supply Al00B :
Overvoltage Alarm Scenarios Inspection Troubleshooting The input voltage of the main circuit exceeds the allowable value Check if the main circuit voltage is within the allowable range Use the correct power supply Power input error Check whether the power supply conforms to the specification required Use the correct power supply Motor decelerates too fast Check if the system inertia is too large and decelerates too fast Extend deceleration time or use an appropriate external braking resistor The load inertia is large and no braking resistor is connected.
Check if overvoltage occurs at stop Install a braking resistor with appropriate capacity and resistance value, and set the braking resistor parameters correctly. Drive hardware failure This alarm still occurs when the main circuit voltage is within the allowable range and the motor is not running Send it to distributor or manufacturer for overhaul.
