Cause : Drive module temperature is excessive.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See the appropriate Hardware
Manual.
Check value of parameter 95.03 Temp
inu ambient.
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.
