Troubleshooting
5.1 Fault Codes Description
Fault
code
Fault type Possible reasons Solution
E001
Invert cells
fault
1.Too fast acceleration 1.Increase acceleration time
2.IGBT inside broken 2.Seek for support
3.Malfunction caused by
interference
3.Check whether peripheral
equipments have strong interference
source
4..Sound grounding or not 4.Check grounding line
E002
Over
current in
accelerated
running
1.Too fast acceleration 1.Increase acceleration time
2.Too low grid voltage 2.Check input power
3.The power of the SPD is too
low
3.Use bigger power SPD
E003
Over
current in
decelerated
running
1.Too fast deceleration 1.Increase deceleration time
2.The inertia torque of load is
too big.
2.Add proper dynamic braking
modules
3.The power of the SPD is too
low
3.Increase power of the SPD
E004
Over
current in
constant
speed
running
1.Saltation or abnormality
happens to load
1.Check the load or decrease the
saltation of the load
2.The grid voltage is too low 2.Check input power supply
