CS3E-E Series EtherCAT Closed Loop stepper drive User Manual
5 Error Code & Trouble Shooting
When an alarm is occurred, the drive turns on the protection function and the motor stops running. CS3E-E
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 0x3FFE+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
1. Check whether the wiring is short-circuited, or the motor is
short-circuited.
2. Switch power supply alarm caused, replace other power
supply for a try.
1. Check the voltage of power supply;
2. If over-voltage occurs in motion, the acceleration and
deceleration time can be increased
1. Reset parameters to the factory and restart power supply
2. If it still exists,the hardware failure
1. Reduce command speed value;
2. Write 0x10 to the object 0x2056 to clear the alarm.
1. Reset parameters to the factory and restart power supply
2. If it still exists,the hardware failure
1. Restart the drive;
2. If it still exists,disable auto-tuning by 0x2013
1. The drive is not connected to a motor;
2. If alarm is occurred when connect a motor, please check
the encoder wiring or a cable break.
Invalid mailbox configuration in
pre-operation state
1. Set the value of Object 2024h to ā0ā to make motor run in
open loop mode, If alarm disappears, it means encoder wiring
error;
2. Motor torque is not enough or motor speed is too high;
Invalid DC synchronization period
Decrease the value of the synchronization period or increase
the value of 0x5400+02
Unsupported operation mode
Check the value of 0x6061 and correct it to the supported
operation mode;
ESM state machine transition failed
Alarms related to the master station, without accurate
solution.
The mapping object does not exist
PDO mapping object length error
PDO mapping object has no mapping
attribute
Invalid ESM conversion request
Unknown ESM conversion request
Boot state request protection
