Description
Possible Causes
Solutions
No braking unit and
braking resistor installed
Install braking unit and braking resistor
E07
Overvoltage at
constant speed
Input voltage is too high
Adjust input voltage to a proper range
E08
Snubber resistor
overload
The input voltage is not
within the specified
range
Adjust input voltage to a proper range
E09
Low input
voltage
The input voltage is not
within the specified
range
Adjust input voltage to a proper range
Abnormal bus voltage
detection; abnormality of
rectifier bridge, snubber
resistor, drive board and
control board
Seek for technical support
E10
Controller
overload
Load is too large or
motor is stuch
Reduce load and check motor and
mechanical condition
Controller model is too
small
Select the controller that matches the
motor power and load conditions
E11
Motor overload
The motor overload
protection parameters
(FA.01-FA.02) are not
properly set
Correctly set them
Load is too large or
motor is stuch
Reduce load and check motor and
mechanical condition
E12
Input phase loss
Abnormal three-phase
input power
Check and troubleshoot existing problems
in peripheral circuits
Failure of drive board or
control board
Seek for technical support
E13
Output phase
loss
Motor failure
Check if the motor winding is open
The wirings between
controller and motor is
abnormal
Troubleshoot peripherals
When the motor is
running, the three-phase
output of the controller is
unbalanced
Check whether the three-phase windings
of the motor are normal and troubleshoot
Failure of IGBT or drive
board
Seek for technical support
E14
IGBT overheat
Ambient temperature is
too high
Lower ambient temperature
Air duct blocked
Clear air duct
Fan failure
Replace the fan
Failure of thermistor or
IGBT
Seek for technical support
E15
External alarm
input
Input external fault signal
through DI terminal
Clear external fault signal
