Possible causes
Solutions
or the motor stall occurs
2.the type selection of inverter
is small
check the motor and its
mechanical conditions
2.choose the inverter with
large power level
41 Err.41
Switch motor
when running
fault
Change current motor through
the terminal when the inverter
is running
Switch motor after the
inverter stops
42 Err.42
Too large speed
deviation fault
1.the setting for Too Large
Speed Deviation
parameters(F8.15, F8.16) is
unreasonable.
2.the setting for encoder
parameters is incorrect
3.the parameter was not
identified
1.reasonably set the
detection parameters
2.correctly set encoder
parameters
3.perform identification
for the motor parameters
43 Err.43
Motor over
speed fault
1.the parameter was not
identified
2.the setting for encoder
parameters is incorrect
3.the setting for motor
overspeed detection
parameter(F8.13, F8.14) is
unreasonable.
1.perform identification
for the motor parameters
2.correctly set encoder
parameters
3.reasonably set the
detection parameters
45 Err.45
Motor
overtemperatur
e fault
1.the wiring of temperature
sensor is loose
2.the motor temperature is too
high
1.detect the wiring of
temperature sensor wiring
and eliminate fault.
2.decrease carrier
frequency or take other
cooling measures to cool
motor
51 Err.51
Initial position
error
the deviation between the
motor parameters and the
actual parameters is too large
reconfirm the correct
motor parameters, focus
on whether the rated
current is set to too small.
