5 Error Code & Trouble Shooting
When an alarm is occurred, the drive turns on the protection function and the motor stops
running. EM3E has three object dictionaries that can read alarm code, and two red LED lights
flash to display some of the alarm information.
5.1 Error Code
(1) Object 01 indicates the current failure alarm, and other sub-index indications are
historical alarms.
(2) Object 0x1001 and 0x603F indicate the current failure alarm, The error code read by
0x603F is IEC 61800 specification; the error code read by 0x1001 is CIA specification.
(3) Error code read by some master station is displayed in decimal. At this time, please convert
it to hexadecimal and then refer to the error code table as below. For example, the master
station reports error code of 8721, the corresponding hexadecimal number is 0x2211, so the
alarm information in the reference table is over-current alarm.
Error code table:
