arrival
Cause
 The time of overload running is
too long.
 SI external fault input terminals
act
 The baud rate setting is
incorrect.
 Fault occurs to the
communication wiring.
 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 modifying circuit is
abnormal.
 The motor capacity does not
comply with inverter capability
 The rated parameter of the motor
does not set correctly.
 The offset between the
parameters from autotune and
the standard parameter is huge
 Autotune overtime
 Error of controlling the write and
read of the parameters
 Damage to EEPROM
 PID feedback offline
 PID feedback source disappear
 Brake circuit fault or damage to
the brake pipes
 External brake resistor is
insufficient
 The actual running time of the
inverter is above the internal
channel or change the fan
 Low the ambient temperature
 Check and reconnect
 Change the power
 Change the power unit
 Change the main control panel
 Check the external device input
 Set proper baud rate
 Check the communication
connection distribution
 Set proper communication address.
 Chang or replace the connection
distribution or improve the
anti-interference capability.
 Check the connector and re-plug
 Change the Hall
Change the main control panel
 Change the inverter mode
 Set the rated parameter according to
the motor name plate
 Empty the motor load and re-identify
 Check the motor connection and set
the parameter.
 Check if the upper limit frequency is
above 2/3 of the rated frequency.
 Press STOP/RST to reset
 Change the main control panel
 Check the PID feedback signal
 Check the PID feedback source
 Check the brake unit and , change
new brake pipe
 Increase the brake resistor
 Ask for the supplier and adjust the
setting running time.
