deceleration time is too
short.
2.
In the V/F drive mode, the
V/F curve setting is
unreasonable.
3.
The load is too heavy.
4.
The braking time is too long,
the braking intensity is too
high, or DC braking is
enabled repeatedly.
deceleration time.
2.
Reasonably set the V/F
curve.
3.
Use the inverter that matches
the load.
4.
Reduce the braking time and
braking intensity. Do not
enable DC braking
repeatedly.
E10
Inverter overheat
1.
The ambient temperature is
too high.
2.
The inverter is subject to
poor ventilation.
3.
The cooling fan fails.
1.
The operating environment
of the inverter should meet
the specifications.
2.
Improve the ventilation
environment and check
whether the air duct is
blocked.
3.
Replace the cooling fan.
E11
Parameter setting
conflict
1.
There is a logic conflict in
parameter settings.
1.
Check whether parameters
set are illogical before the
occurrence of fault.
E13
Motor overload
1.
The acceleration and
deceleration time is too short.
2.
In the V/F drive mode, the
V/F curve setting is
unreasonable.
3.
The load is too heavy.
1.
Increase the acceleration and
deceleration time.
2.
Reasonably set the V/F
curve.
3.
Use a motor matching the
load.
E14
External fault
1.
The external device fails,
resulting in the terminal
action.
1.
Check the external device.
E15
Inverter memory
failure
1.
Interference results in
memory reading and writing
errors.
2.
The internal memory of the
controller is read and written
repeatedly, causing damage
to the memory.
1.
Press the STOP/RESET key
to reset the controller and try
again.
2.
For the parameters (e.g.
frequency setting) to be
modified frequently, set
F10.56 to 11 after debugging.
E16
Communication
error
1.
Communication timeout is
enabled in the discontinuous
communication system.
2.
Communication is
disconnected.
1.
F10.03 is set to 0.0 in the
discontinuous
communication system.
2.
Adjust the F10.03
communication timeout.
3.
Check whether the
