13 Er.oLP
1: The cable connecting the frequency
inverter and the motor is faulty.
2: The frequency inverter's
three-phase outputs are unbalanced
when the motor is running.
3: The drive board is faulty.
4: The IGBT module is faulty.
1:Eliminate external faults.
2: Check whether the
Motor three phase winding
is normal.
3: Ask for technical support.
4: Ask for technical support.
IGBT Module
overheat
14 Er. oH
1: The ambient temperature is too
high.
2: The air filter is blocked.
3: The fan is damaged.
4: The thermally sensitive resistor of
the IGBT module is damaged.
5: The inverter IGBT module is
damaged
1:Lower the ambient
temperature.
2: Clean theairfilter.
3: Replace thedamaged fan.
4: Replace the damaged
thermally
sensitive resistor.
5: Replace the inverter module.
Motor
overheat
16 Er. oH3
1:the temperature sensor wiring is
loose
2:the motor temperature is too high
3:Themotor temperature sensor detects
that the temperature is greater than the
set threshold.
1:check the temperature sensor
wiring
2:Improve the carrier
frequency, strengthen the heat
dissipation of the motor, reduce
the load, and select a motor
with higher power.
3:Check if the set threshold is
reasonable.

17 Er.CbC
1: The load is too heavy or locked-
rotor occurs on the motor.
2: The frequency inverter model is of
too small power class
1: Reduce the load and check
the motor and mechanical
condition.
2: Select a frequency inverter of
higher power class.
