Solution
Check the grid voltage;
Select the inverter with larger
power;
Select a proper motor.
Check the input power;
Check the installation wiring.
Check the output wiring;
Check the motor and cables.
Ventilate the air duct or replace
the fan;
Lower the ambient temperature.
Check external device input.
Set proper baud rate;
Check the
communication interfaces;
Set the communication address
correctly;
Replace or change the wiring to
enhance the anti-interference
capacity.
Check the connector
re-plug;
Replace the hall component;
to
Replace the main control board.
Change the inverter model;
Set proper motor type and
nameplate parameters;
set
Empty the motor load and carry
out autotuning again;
Check the motor wiring and
parameter setup;
Check whether the upper limit
frequency is larger than 2/3 of
the rated frequency.
