fault
Cause
The acceleration is too fast
There is damage to the
internal to IGBT of the phase
The connection of the driving
wires is not good
The grounding is not good
The acceleration or
deceleration is too fast
The voltage of the grid is too
low
The power of the inverter is
too low
The load transients or is
abnormal
The grounding is short
circuited or the output is
phase loss
There is strong external
interference
The overvoltage stall
protection is not open
The input voltage is
abnormal
There is large energy
feedback
No braking components
Braking energy is not open
The voltage of the power
supply is too low
The overvoltage stall
protection is not open

Fault tracking
Solution

Increase Acc time

Change the power unit

Check the driving wires

Check if there is strong
interference to the external
equipment
Increase the ACC time
Check the input power
Select the inverter with a larger
power
Check if the load is short
circuited (the grounding short
circuited or the wire short
circuited) or the rotation is not
smooth
Check the output configuration.
Check if there is strong
interference
Check the setting of relative
function codes
Check the input power
Check if the DEC time of the
load is too short or the inverter
starts during the rotation of the
motor or it needs to increase the
energy consumption
components
Install the braking components
Check the setting of relative
function codes
Check the input power of the
supply line
Check the setting of relative
function codes
