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
up
internally set time.

The VFD reports overload
pre-alarm according to the
set value.

Keypad wire is poorly
contacted or disconnected.

Keypad wire is too long
and suffers strong
interference.

Keypad or communication
circuit is faulty.

Solution
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 keypad wire and
confirm whether fault exists.
Check the environment and
rule out interference
source.
Replace the hardware, and
ask for maintenance
service.
