operation fault
Possible cause

SI external fault input
terminals acts.

The baud rate setting is
incorrect;

Fault occurs to the
communication circuit;

The communication
address is wrong;

There is strong
interference to the
communication.

The connection of the
control board is not good;

Assistant power is bad;

Hall components is
broken;

The magnifying circuit is
abnormal.

The motor capacity does
not match with VFD
capacity;

The rated parameter of the
motor is set improperly;

The deviation between the
parameters from autotune
and the standard
parameter is huge;

Autotune overtime.

Error occurred to R/W of
the control parameter;

EEPROM is damaged.
