Cause
Calculated motor cable
temperature has exceeded
warning limit.
temperature is excessive.
Drive module temperature is
excessive.
Drive IGBT temperature is
excessive.
Power unit module
temperature is excessive.
High temperature difference
between the IGBTs of different
phases.
Measured temperature 1 has
exceeded fault limit.
Measured temperature 2 has
exceeded fault limit.
A thermistor protection module
has been activated by
parameter 35.30 but cannot be
detected.
What to do
Check the settings of parameters
and 35.62.
Check the dimensioning of the motor
cable in regard to required load.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware manual.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
See A4B0 Excess temperature
497).
See A4B1 Excess temperature
difference (page 497).
Check the value of parameter
Measured temperature 1.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
Temperature 1 fault limit.
Check the value of parameter
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
Temperature 2 fault limit.
Power down the control unit and make
sure that the module is properly inserted
in the correct slot.
The last digit of the auxiliary code
identifies the slot.
