Fault
code
Fault type Possible reasons Solution
4．Overload 4．Use bigger power SPD
E011
Motor
overload
1．The grid voltage is too low 1．Check grid voltage
2．Wrong setting to motor rated
current
2．Reset motor rated current
3．Motor stall or big changes to
load
3．Check the load and adjust torque
lifting capacity
4．Motor is too small 4．Use proper motor
E013
Output
phase loss
U,V,W phase loss output(or the
three phases of load is not
symmetrical)
1．Check output wiring
2．Check motor and cable
E014
Module
overheatin
g
1．Instant over current of SPD 1．Refer to over current solutions
2．Output three phases have
interphase or ground is short
circuit
2．Re-wiring
3．Air passage block or fan
broken
3．Dredge air passage or change fan
4．The environmental
temperature is too high
4．Decrease environmental
temperature
5．SPD wire or plugins loose 5．Check and re-connect
6．Power circuit irregularity 6．Seek for service
