1: The cabling of the temperature
sensor becomes loose.
2: The motor temperature is too
high.
1: The motor parameters are not
set based on the actual situation.
1: The PID feedback is lower than
the setting of PA-27.
1: The load is too heavy or
lockedrotor occurs on the motor.
2: The AC drive model is of too
small power class.
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
performed.
3: P9-42 and P9-43 are set
incorrectly.
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
performed.
3: P9-40 and P9-41 are set
incorrectly
1: Check the temperature sensor cabling
and eliminate the cabling fault.
2: Lower the carrier frequency or adopt
other heat radiation measures.
1: Check the motor para-meters are set
correctly and whether the setting of rated
current is too small.
1: Check the PID feedback signal or set
PA-27 to a proper value.
1: Reduce the load and check the motor and
mechanical condition.
2: Select the AC drive of higher power
class.
1: Set the encoder parameters properly.
2: Perform the motor autotuning.
3: Set F9-69 and F9-70 correctly based on
the actual situation.
1: Set the encoder parameters properly.
2: Perform the motor autotuning.
3: Set P9-40 and P9-41 correctly based on
the actual situation.

If the carrier frequency is set higher than
the factory value, it will cause the tempe-
rature rise of the converter radiator to
increase. At this time, the user needs to use
the converter derating, otherwise the conver-
ter will have the danger of overheating alarm.
