Cause
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
cannot be detected.
The thermistor protection module
installed in slot 1 indicates
overtemperature.
The thermistor protection module
installed in slot 2 indicates
overtemperature.
What to do
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.
