EA180 Series Servo Drive Users Manual 104 Al034 : Analog zero drift correction error Alarm Scenarios Inspection Troubleshooting When performing zero drift self-learning, the collected external voltage exceeds 2V When performing zero drift self-learning, whether to set the upper device command to 0 Set the upper device command to 0, and then carry out zero drift self-learning again. Check if the output voltage exceed 2V when the command of the upper device is 0 Correct the output of the upper device Al038 :

The relay is not fully engaged Alarm Scenarios Inspection Troubleshooting The soft start relay of the servo main circuit is not fully engaged Check if the alarm is eliminated after power-on again Send it to the distributor or the manufacturer for overhaul. Al039 : Serial encoder line number setting error Alarm Scenarios Inspection Troubleshooting The number of serial encoder lines is set incorrectly by user Check related parameters Set them correctly The number of lines shall be one-fourth of the standard number of lines of encoder Al040 : Write motor encoder EEPROM error Alarm Scenarios Inspection Troubleshooting An error occurred while writing parameters to the motor encoder 1:

Check whether the communication protocol of the encoder meets the requirements. 2: Check whether the encoder cable is correctly and well connected. Re-perform the write operation Al041 : Read motor encoder EEPROM error Alarm Scenarios Inspection Troubleshooting An error occurred while reading parameters from the motor encoder 1: Check whether the communication protocol of the encoder meets the requirements. 2: Check whether the encoder cable is correctly and well connected. Re-execute the read operation, if unsuccessful, use the motor CODE Al042 :

Read motor encoder EEPROM check error Alarm Scenarios Inspection Troubleshooting The parameter read from the motor encoder is not checked correctly, or no parameter is written in the encoder. 1: Check whether the encoder cable is correctly and well connected. Re-execute the read operation, if unsuccessful, use the motor CODE Al043 : Pulse given direction signal error Alarm Scenarios Inspection Troubleshooting When the pulse + direction given position command is used, the drive detects that the direction signal changes frequently during the power-on and initialization process, and the real state of the direction signal cannot be determined. 1:

Check whether the pulse command cable is correctly and well connected. 2: Check whether there is serious interference. 3: Check whether the output of the upper device is normal 1: Take appropriate anti-interference measures. 2: Adjust the setting value of P1-15 to filter out interference.
