AL.017 Abnormal EEPROM – Delta servo troubleshooting

<= See All alarms of Delta servo

Name Description ALM WRN SRV ON Clear


Abnormal EEPROM

It is in error when DSP accesses EEPROM   No If the alarm occurs,then parameter
reset is a must. And re-servo on
again. If it happens during the operation, please turn DI.ARST on to clear the alarm.

Causes Checking Method Actions
It is in error when DSP accesses EEPROM Press the SHIFT Key on the panel and it shows EXGAB. X = 1, 2, 3
G=group code of the parameterAB=hexadecimal of the parameterIf it shows E320A, it means it is parameter P2-10; If it shows E3610, it means it is parameter P6-16. Please check the parameter
The fault occurs when applying to the power. It means one of the parameters is over the reasonable range. Please re-power on after adjusting. The fault occurs in normal operation. It means it is in error when writing the parameter. The alarm can be cleared by DI.ARST
Abnormal hidden parameter Press the SHIFT Key on the panel and it shows E100X The fault occurs in parameter reset.The setting of the drive is wrong. Please set the correct type of the drive
Data in ROM is damaged Press the SHIFT Key on the panel and it shows E0001 The fault occurs when it is servoon. Usually it is because the data in ROM is damaged or there is no data in ROM. Please send the drive back to the distributors or contact with Delta

Other reasons Checking Method Actions
Data corruption in EEPROM or abnormality after upgrade(Archer) Press ‘Shift’ button of panel and display EXGBA defined as above Set P2-08 = 10 to reload parameters to default and then re-power on
EEPROM damaged (Archer) Is the host computer (such as PLC) constantly writing parameters to cause the EEPROM to be damaged due to too many writes? Check the host controller’s program to avoid continuous writing parameters (unless the parameter attribute is volatile), or set P2-30=5 to force all parameters not to be written to EEPROM.
