Fault
code
Fault type Possible reasons Solution
3．The power of the SPD is too
low
3．Use bigger power SPD
E005
Over
voltage in
accelerated
running
1．The input voltage is abnormal 1．Check input power supply
2．Restart rotating motor after
momentary outages
2．Avoid restarting after it is stopped
E006
Over
voltage in
decelerated
running
1．Too fast deceleration 1．Increase acceleration time
2．The inertia of load is too big 2．Increase dynamic braking modules
3．The input voltage is abnormal. 3．Check input power
E007
Over
voltage in
constant
speed
running
1．Abnormal changes happen to
input voltage
1．Install input reactor
2．The inertia of load is too big
2．Add proper dynamic braking
modules
