Chapter VII Troubleshooting
7.1 Failure Reasons and Countermeasures
When any abnormality occurs to driver, LED digital tube will display a
corresponding failure code, failure relay will act, and driver will stop output,
before failure, if motor is rotating, it will stop at random, till it stops rotating.
When any failure occurs to driver, users need to find out failure reasons and
countermeasures corresponding to failure code, and then carry out troubleshooting,
when technical service is needed, please contact after-sale services or agents of
our company.

E-01
Over-current
during
acceleration
running
①
Acceleration time too short;
②
Over large load inertia;
③
Over low power grid voltage;
④
Driver power too small;
⑤
Restart motor during rotating.
①
Extend acceleration time;
②
Decrease load inertia;
③
Check input power supply;
④
Select drivers with large
power grade;
E-02
Over-current
during
deceleration
running
①
Deceleration time too short;
②
There’re loads with large
inertia;
③
Driver power too small.
①
Extend deceleration time
;
②
Decrease load inertia;
③
Select drivers with large
power grade.
E-03
Over-current
during constant
speed running
①
Input voltage abnormal;
②
Load mutation or abnormal
load;
③
Driver power too small
①
Check input power supply;
②
Check load or decrease load
mutation;
③
Select drivers with large
power grade;
