Display Fault Name Possible Causes Solutions
Er/AL27
Motor
overheat
The cabling of the temperature
sensor becomes loose.
Check the temperature sensor
cabling and eliminate the
cabling fault.
The motor temperature is too high.
Lower the carrier frequency or
adopt other heat radiation
measures.
Er28
Motor short
circuit to
ground fault
The motor is short circuited to the
ground.
Replace the cable or motor.

the setting of E5.33 or lower than
the setting of E5.34. Check the PID feedback signal
or set E5.33 and E5.34 to a
proper value.
The parameters of PID are set
incorrectly. Set the PID parameters
properly.
