short-circuit fault 1
Possible cause
• Motor parameters are set
improperly.
• The deviation between the
parameters obtained from
autotuning and the
standard parameter is
huge.
• Autotuning timeout.
• Error occurred to the
writing/reading of control
parameters.
• EEPROM damaged.
• PID feedback offline.
• PID feedback source
disappears
The actual running time of the
VFD is larger than the
internally set time.
The VFD reports overload
pre-alarm according to the
set value.
Input grid overvoltage.
Input overvoltage threshold
(P18.46) is set improperly.
Input grid undervoltage.
Input undervoltage threshold
(P18.47) is not set improperly.
• VFD output is short
circuited to ground.
• Current detection circuit is
-104-

nameplate parameters
correctly.
• Empty the motor load and
identify again.
• Check the motor wiring and
parameter setup.
• Check whether upper limit
frequency is larger than 2/3
of the rated frequency.
• Press STOP/RST to reset.
• Replace the main control
board.
• Check PID feedback signal
wire.
• Check PID feedback source
• Ask supplier for help.
• Adjust the set running time.
Check the load and overload
pre-alarm threshold.
• Check the input grid power
supply.
• Check the installation and
wiring.
• Ensure the setting value of
P18.46 is proper.
• Check the input grid power
supply.
• Check the installation and
wiring.
• Ensure the setting value of
P18.47 is proper.
• Check whether motor wiring
is normal/motor is short
circuited to ground.
