Troubleshooting
Note: This error is reported after the communication data is incorrect and exceeds the time set by F12.06 [Modbus Communication Timeout].
The motor action can be detected when this fault is detected by F12.07 [Communication Disconnection Processing].

Module overheat warning
Note: When the module temperature exceeds F10.25 [drive overheat warning detection level], the warning is reported. If the module temperature continues
to rise, the overheat fault E.OH1 will be triggered.

Motor overheat warning
Note: This warning is reported when the motor temperature exceeds F10.27 [Motor overheat warning detection level].
Select which temperature sensor (PT1000/KTY84) to use by F10.26 [Motor overheat protection selection], and F10.26 [Motor overheat protection
selection] ten setting to detect the motor action when this fault is detected.
This function needs to be implemented with an IO expansion card.

6.6 Fault reset method
When the drive has a fault and stops running, please follow the steps below to find out the cause and restart the drive after taking appropriate
countermeasures.
AC10 Series Frequency Inverter Technical Manual
Reason
There is a strong interference source that causes
problems with data transmission.
A
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
Ambient temperature is too high
Excessive load
Fan failure
Reason
Motor heat transfer is abnormal
Excessive load
Reason
There is a shutdown signal externally, but the running
command is valid at this time.
Reason
After the start protection is turned on, the drive will exit
start
the abnormal click terminal and the effective warning
prompt
Reason
After the start protection is turned on, the terminal will
be valid when the drive exits abnormally.
Reason
There is a strong interference source that causes
problems with data transmission.
External keyboard wiring is incorrect or disconnected
Reason
The monitoring value 1 set by F06.50[Comparator 1
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
2
monitor selection] exceeds F06.56 [Comparator 2
upper limit] and F06.57 [Comparator 2 upper limit].
Countermeasures
Check the grounding of the whole machine to
eliminate the interference source
Check if there is a problem with the expansion card A
wiring.
Countermeasures
Check the grounding of the whole machine to
eliminate the interference source
Check if there is a problem with the expansion card B
wiring.
Countermeasures
Check the grounding of the whole machine to
eliminate the interference source
Check if there is a problem with the CAN expansion
card wiring
Countermeasures
Reduce the ambient temperature of the drive
Reduce the load
Check whether the fan is running normally. If the fan is
abnormal, you need to replace the fan and then power
on.
Countermeasures
Improve motor cooling
Reduce the load
Countermeasures
Restart after removing the external stop signal
Countermeasures
First undo the jog terminal command and then re-
given the jog run command
Countermeasures
First cancel the terminal command and re-given the
terminal to run the command.
Countermeasures
Eliminate interference sources
Check if there is a problem with the external keyboard
connection, re-plug the keyboard, still can not solve
the problem of seeking external technical support for
the manufacturer.
Countermeasures
Check the status of the monitor value 1 and eliminate
the cause of the warning.
Countermeasures
Check the status of monitor value 2 and eliminate the
cause of the warning.
