Possible Causes
Solutions
Accumulative
power-on time
reached
Err29
The accumulative power-on time reaches
the setting value.
Clear the record through the
parameter initialization function
Load becoming 0 Err30
The AC drive running current is lower than
P9-64.
Check that the load is
disconnected or the setting of
P9-64 and P9-65 is correct.
PID feedback lost
during running
Err31
The PID feedback is lower than the setting
of PA-26.
Check the PID feedback signal or
set PA-26 to a proper value.
Pulse-by-pulse
current limit fault
Err40
1: The load is too heavy or locked-rotor
occurs on the motor.
2: The AC drive model is of too small power
class.
1: Reduce the load and check the
motor and mechanical condition.
2: Select an AC drive of higher
power class.
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.
Too large speed
deviation
Err42
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not performed.
3: P9-69 and P9-70 are set incorrectly.
1: Set the encoder parameters
properly.
2: Perform the motor auto-tuning.
3: Set P9-69 and P9-70 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: P9-69 and P9-70 are set
incorrectly.
1: Set the encoder parameters
properly.
2: Perform the motor auto-tuning.
3: Set P9-69 and P9-70 correctly
based on the actual situation.
