No Fault Code Possible Causes Solutions
Fault Type
◆ Check the connector and
repatch;
◆ Replace Hoare current
sensor;
◆ Replace the main control
board.
External fault

communi-
cation fault
◆ Set proper baud rate;
◆ Check the communication
interface wiring;
◆ Set the correct
communication address
◆ Replace or change the
wiring, improve anti-
interference capability.
◆ Lower ambient
temperature
◆ Check input power of
supply line
◆ The baud rate setting is
incorrect;
◆ Communication wire
failure;
◆ The communication
address is wrong;
◆ There is strong interferen-
ce to the communication.
◆ The connection of
control board is not good;
◆ Hoare components are
broken;
◆ The modifying circuit is
abnormal.
◆ Ambient temperature is
too high;
◆ The time of overload
running is too long.

◆ There is an error in read-
write control parameter;
◆ EEPROM is damaged.
◆ Press STOP/RST to reset;
◆ Replace the main control
board
◆ PID feedback offline;

Troubleshooting
◆ Check input power of
supply line.
◆ U, V, W phase loss

metrical three-phase of
the load). Output

◆ Increase the acceleration
time;
◆ Avoid restart after stopping;
◆ Check the power of the
supply line;
◆ Select a AC drive with
bigger power;
◆ Select a proper motor.
◆ The acceleration is too
short;
◆ Reset the rotating motor;
◆ The voltage of power
supply is too low;
◆ The load is too heavy;
◆ Close loop vector control,
reverse direction of the
code panel and long low-
speed operation.
