Fault description
Possible causes
Remedy
Lower-rating controller
Replace with higher-rating
controller
Err05
Over-voltage during
acceleration
Abnormal input voltage
Check input power
Restart the motor when
instantaneous trip-off occurs
Avoid prompt restart when
trip-off
Err06
Over-voltage during
deceleration
Too-fast deceleration
Add proper braking units
Abnormal input voltage
Check input power supply or
wiring
Err07
Over-voltage at
constant running
speed
Abnormal input voltage
Adjust input voltage to
normal range
Err0
8
Overload of buffer
resistor
Abnormal input voltage
Adjust input voltage to
normal range
Err09 Under voltage of
DC bus
Too-low input voltage
Check input power supply or
wiring
Err10 Controller overload
Too fast acceleration
Increase acceleration time
Restart the motor when
instantaneous trip-off occurs
Avoid prompt restart when
trip-off
Too-low input voltage
Check input power supply or
wiring
Too-heavy load
Replace with higher-rating
controller
Err11 Motor overload
Incorrect setting of
FA.01&FA.02
Set the parameters correctly
Load too heavy or motor stuck
Reduce load
，
or check the
motor
Err12 Input phase loss
Abnormal input power source
Check input power source
and wiring
