Chapter 12 Inverter Function
12.19.2 Outputting a serious fault signal
• I want to detect the unrecoverable error state of
the inverter and make a notification to the system.
• Assign the output terminal function 018 [MJA]
serious fault signal to one of [CC-01] to [CC-07]
that corresponds to the output terminal and output
the signal.
• Trips that are evaluated as serious faults are as
follows.
Parameter
• The inverter hardware may have a fault when this
signal is output. Check the error history and deal
with the situation appropriately.
Error code Name Description
E008 Memory element error The memory element of the inverter is under an abnormal condition.
E010 Current detector error The current detector of the inverter is under an abnormal condition.
E011 CPU error The drive CPU of the inverter is under an abnormal condition.
E014 Ground fault error The inverter has a ground fault.
E019
Temperature detector
error
The temperature detector of the inverter is under an abnormal condition.
E020
Cooling fan rotation
speed reduction error The cooling fan rotation speed of the inverter has reduced, preventing the
inverter from dissipating heat.
