6.2 Common fault and solutions
During the inverter using process, the following faults may occur. Please conduct simple
fault analysis by referring to the methods below
：
No.
Fault
Phenomenon
Possible Cause Solution
1
No display or error
codes occur upon
power-on
Abnormal input power
supply,switch power supply fault
of driven board, rectifier bridge
damage,
inverter buffer
resistance damage, control
board/keyboard fault, control
board/driven board/keyboard
disconnection
Check inputpower supply, bus voltage,
re-plug
26 core cable,
consultthemanufacturer
2
Display“510” upon
power-on
Poor contact between driven
board and control board, device
damage on control board, motor
or motor cable short circuited, hall
fault, grid undervoltage
Re-plug 26 core cable,
consult the manufacturer
3
“Error 23=Err23”
alarming upon power on
The motor or the output line is
short circuited to the earth
、
the
inverter is damaged.
Measure the insulationof the motor and
output line with magneto-ohmmeter,
consult themanufacturer.
4
The inverter displays
normally upon power-
on, but “510” is
displayed upon running
and stops immediately
The fan is either damaged or
blocked,
peripheral
controlterminalshortcircuited
Replace the fan,exclude external short-
circuit fault
5
Frequent fault report
ERR14=Err14 (module
overheating)
The carrier frequency is set too
high, the fan is damaged or the air
duct is blocked, inverter internal
components damaged
Replace the fan,clean air duct, reduce
carrier
frequency(P0.15) ,consultmanufacturer.
6
Motor no rotating after
inverter power-on
Motor or motor cable, wrongly
set inverter parameters(motor
parameter), poor contact
between driven board and
control board, driven board fault
Replace the motor orremove the
mechanical fault, check and reset the
parameters, confirm connection between
inverter and motor
7 DI terminal invalid
Wrongly set inverter parameters,
wrong external signal, SP and Check and reset the P4relevant
parameters,reconnect cables, reconfirm
