Possible Causes
1: The user-defined fault 2 signal
is input via DI.
Err28
2: The user-defined fault 2 signal
is input via virtual I/O.
1: The AC drive running current is
Err30
lower than P9-64.
1: The PID feedback is lower than
Err31
the setting of PA-26.
1: The load is too heavy or
locked-rotor occurs on the motor.
Err40
2: The AC drive model is of too
small power class.
1: The cabling of the temperature
sensor becomes loose.
Err45
2: The motor temperature is too
high.
1: The motor parameters are not
Err51
set based on the actual situation.
1: Reset the operation.
2: Reset the operation.
1: Check that the load is
disconnected or the setting of
P9-64 and P9-65 is correct.
1: Check the PID feedback
signal or set PA-26 to a
proper value.
1: Reduce the load and
check the motor and
mechanical condition.
2: Select an AC drive of
higher power class.
1: Check the temperature
sensor cabling and eliminate
the cabling fault.
2: Lower the carrier
frequency or adopt other
heat radiation measures.
1: Check that the motor
parameters are set correctly
and whether the setting of
rated current is too small.
