Braking circuit fault or
damage to the braking pipes
The external braking resistor
is not sufficient
The output of the inverter is
short circuited with the
ground.
There is fault in the current
detection circuit.
The actual motor power
sharply differs from the
inverter power.
The output of the inverter is
short circuited with the
ground.
There is fault in the current
detection circuit.
The actual motor power
sharply differs from the
inverter power.
The load is too heavy or
stalled.
The control parameters of
the synchronous motors not
set properly.
The autoturn parameter is
not right.
The inverter is not connected
to the motor.

Fault tracking
Check the braking unit and ,
change new braking pipe
Increase the braking resistor
Check if the connection of the
motor is normal or not
Change the hall
Change the main control panel
Set motor parameters correctly.
Check if the connection of the
motor is normal or not
Change the Hall
Change the main control panel
Set motor parameters correctly.
Check the load and ensure it is
normal. Increase the detection
time.
Check whether the control
parameters are normal.
Check the load and ensure it is
normal.
Check whether the control
parameter is set properly or not.
Increase the maladjustment
detection time.
