Cooling
Drive module temperature is
excessive.
Check ambient temperature. If it exceeds
40 °C, 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.
