LVLQSXWYLDYLUWXDO,2
Reset the operation.
Accumulative
power-on time
reached
Err29
The accumulative power-on time
reaches the setting value.
Clear the record through
the parameter initialization
function.
Load lost Err30
The AC drive running current is
lower than F9-64.
Check that the load is
disconnected or the setting of
F9-64 and F9-65 is correct.
PID feedback lost
during running
Err31
The PID feedback is lower than
the setting of FA-26.
Check the PID feedback
signal or set FA-26 to a
proper value.
Pulse-by-pulse
current limit fault
Err40
1: The load is too heavy or motor
standstill occurs..
2: The AC drive size is small.
1: Reduce the load and
check the motor and
mechanical condition.
2: Replace a large drive.
Motor switchover
fault during
running
Err41
Change the selection of the motor
via terminal during running of the
AC drive.
Perform motor switchover
after the AC drive stops.
Speed feedback
error too large
Err42
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
performed.
3: F9-69 and F9-70 are set
incorrectly.
1: Set the encoder
parameters properly.
2: Perform the motor auto-
tuning.
3: Set F9-69 and F9-70
correctly based on the actual
situation.
Motor over-speed Err43
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
performed.3: F9-69 and F9-70 are
set incorrectly.
1: Set the encoder
parameters properly.
2: Perform the motor auto-
tuning.
3: Set F9-69 and F9-70
correctly based on the actual
situation.
Motor overheat Err45
1: The cabling of the temperature
sensor becomes loose.
2: The motor temperature is too high.
1: Check the temperature
sensor cabling and eliminate
the cabling fault.
2: Lower the carrier
frequency or adopt other
heat radiation measures.
Initial position
fault
Err51
The motor parameters are not set
based on the actual situation.
Check that the motor
parameters are set correctly
and whether the setting of
rated current is too small.
