failure
Improper setting of parameters related to rapid
detection
Note: The percentage of the output motor speed relative to F01.10 [maximum frequency] is greater than F10.44 [flying detection threshold], and the fault
is reported after F10.45 [flying detection time].
This fault detection can be enabled by F10.43 [Fast protection action] and the motor operation mode when the fault is detected can be set.

Reason
A failure occurred on the machine side, such as a
Load
broken belt pulley.
E.LD1
warning 1
Load warning 1 parameter setting is improper
Note: The output current of the drive exceeds F10.33 [load warning detection level 1], and the duration exceeds F10.34 [load warning detection detection
time 1], and the fault is reported.
This fault detection can be enabled by F10.32 [Load Detection Warning Setting] and tens of digits, and the motor operation mode when the fault is detected
can be set.

E.LD2
warning 2
Load warning 2 parameter settings are improper
Note: The drive output current exceeds F10.35 [load warning detection level 2], and the duration exceeds F10.36 [load warning detection detection time
2], and the fault is reported.
The fault detection can be enabled and the motor operation mode when the fault is detected can be enabled by F10.32 [Load Detection Warning Setting]
and hundreds and thousands.

6.5 Warning
When the warning occurs, the drive can continue to operate. The following table explains the cause of the failure and the corresponding measures.
Note: All warnings can be automatically eliminated if they do not meet the detection conditions.
Code
Name
AC10 Series Frequency Inverter Technical Manual
Reason
The chip is subjected to strong interference, causing
software calculation timeout
Chip hardware problem
Reason
Software version does not match the control board
Reason
There is a strong interference source that causes
A
problems with data transmission.
Expansion card A is not wired correctly, or disconnection
occurs
Reason
There is a strong interference source that causes
problems with data transmission.
Expansion card B wiring is incorrect, or disconnection
occurs
Reason
There is a strong interference source that causes
problems with data transmission.
CAN expansion card wiring is incorrect, or disconnection
occurs
Reason
The monitoring value 1 set by F06.50 [Comparator 1 monitor
selection] exceeds F06.51 [Comparator 1 upper limit] and F06.52
[Comparator 1 upper limit].
Reason
The monitoring value 2 set by F06.55 [Comparator 2 monitor
selection] exceeds F06.56 [Comparator 2 upper limit] and F06.57
[Comparator 2 upper limit].
Reason
Parameter value setting error
Reason
Countermeasures
Adjust F02.33 [ABZ encoder line number] or F02.34 [rotation pole
number]
Adjust F10.44 [Flying Detection Threshold] and F10.45 [Fast Detection
Time]
Countermeasures
Confirm the mechanical condition and eliminate the cause of the
malfunction.
Adjust F10.33 [load warning detection level 1] and F10.34 [load warning
detection detection time 1]
Countermeasures
Confirm the mechanical condition and eliminate the cause of the
malfunction.
Adjust F10.35 [load warning detection level 2] and F10.36 [load warning
detection detection time 2]
Countermeasures
Eliminate strong interference sources, power off
and restart
Seek technical support from manufacturers
