Communication
error
1. The baud rate setting is
incorrect.
2. Fault occurs to the
communication wiring.
3. The communication
address is wrong.
4. There is strong
interference to the
communication.
1. Set proper baud rate
2. Check the communication
connection distribution
3. Set proper
communication address.
4. Chang or replace the
connection distribution or
improve the
anti-interference capability.
ItE
Current detection
fault
1. The connection of the
control board is not good
2. Assistant power is bad
3. Hoare components is
broken
4. The modifying circuit is
abnormal.
1. Check the connector and
repatch
2. Change the Hoare
3. Change the main control
panel
tE Autotuning fault
1. The motor capacity does
not comply with the inverter
capability
2. The rated parameter of
the motor does not set
correctly.
3. The offset between the
parameters from autotune
and the standard parameter
is huge
4. Autotune overtime
1. Change the inverter mode
2. Set the ratedparameter
according to the motor
name plate
3. Empty the motor load and
reindentify
4. Check the motor
connection and set the
parameter.
5. Check if the upper limit
frequency is above 2/3 of
the rated frequency.
