Err.27
Running time
reached
1. Accumulative running time
reach to set value
1. Using parameter initialization
function to clear the record
information
Err.28
Power on
time reached
1. Accumulative power on time
reach to set value
1. Using parameter initialization
function to clear the record
information
Err.29
Buffer
contactor
overheating
1. Power grid voltage fluction
range is too large, cause the
inverter repeatedly up and
down, buffer contactor
overheating
1. Adding input reactor and other
measures to ensure the stability of
input voltage
Err.31
Encoder/PG
card anormal
1. Encoder model does not
match
2. Encoder cconnection erro
3. Encoder damage
4. PG card anormal
1. According to the actural set right
encoder type
2. Out of line fault
3. Replace encoder
4. Replace PG card
Err.35
User
self-define
fault 1
1. Through the multi-function
terminal DI input the signal of
user-defined fault 1
2. Through the virtual IO
function input the signal of
user-defined fault 1
1. Reset running
2. Reset running
Err.36
User
self-define
fault 2
1. Through the multi-function
terminal DI input the signal of
user-defined fault 2
2. Through the virtual IO
function input the signal of
user-defined fault 2
1. Reset running
2. Reset running
Err.37
Offload
1. The inverter running current
is less than F8-16
1. Confirm whether the load is out
of or F8-16, F8-17 parameter
settings are consistent with the
actual running condition
Err.38
Rapid
current-limitin
g timeout
1. Whether the load is too large
or motor stalling
2. Small frequency converter
selection
1. Reduce the load and check the
motor and mechanical conditions
2. Selection inverter with bigger
class power
Err.39
Switch motor
when running
1. In the process of inverter
running through the terminal to
change the current motor
selection
1. Switch motor operation after
inverter stop
Err.40
Too large
speed
deviation
1. The encoder parameter
setting is not correct
2. No parameter identification
3. Excessive speed deviation
detection parameters F8-22,
F8-23 set is not reasonable
1. Correctly set the encoder
parameters
2. Doing motor parameter
identification
3. Reasonable set testing
parameters according to the actual
situation
Err.41
Motor
overspeed
1. The encoder parameter
setting is not correct
2. No parameter identification
1. Correctly set the encoder
parameters
2. Doing motor parameter
