of the Bus
Possible cause
1. The acceleration is too
fast.
2. There is damage to the
internal to IGBT of the
phase.
3.The connection of the
driving wires is not good,
4.The grounding is not good
1. The acceleration
deceleration is too fast.
2. 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
circuited or the output is
phase loss.
There is strong external
interference.
1. The input voltage is
abnormal.
2. There is large energy
feedback.
The voltage of the power
supply is too low.

Fault tracking
What to do
1. Increase Acc time.
2. Change the power unit.
3. Check the driving wires.
4. Check if there is strong
interference to the external
equipment.
or 1. Increase the ACC time
2. Check the input power
3. Select the inverter with a
larger power
Check if the load is short
circuited (the
short circuited or the wire
short circuited)
short rotation is not smooth.
Check the
configuration.
Check if there is strong
interference.
1. Check the input power
2. Check if the DEC time of
the load is to short or the
inverter starts during the
rotation of the motor or it
needs to increase the
energy consumption
components.
Check the input power of
the supply line

or the
output
