2.6 Abnormality Handling
For the abnormality handling, first enter the level 1 password, and then modify the parameters
following the steps.
View the fault code with server. Enter menu 322 and view the fault log, of which 3221 first shows the most
recent fault and its occurrence time. Scroll it down to view the historical fault record, and a total of last 16
faults can be recorded. 3222 means the total number of occurrences of each fault. Enter menu 3223 to
clear the fault log, and menu 3224 can clear the number of faults.
Description of fault codes:

overcurrent
Output current of IPM
module exceeds the
rated value
Power wiring on the door operator is
likely to be grounded or short-circled.
Under normal circumstances, the
resistance between the ground wires
should be above MΩ, and the
resistance between the coils should
keep in balance.
Speed of door operator
motor is beyond the
defined speed.
Motor speed may exceed the limit;
Initial angle of motor is incorrect, and
angle learning is necessary.
The voltage of door
operator bus is
detected to be lower
than the upper limit of
specification range.
Check if the input power supply is high
