High-function General-purpose Inverter RX2 Series User’s Manual
Alarm code is used to output the inverter trip factor as a 3-bit or 4-bit code signal.
Assign the output terminal functions 084 [AC0] to 087 [AC3] alarm code to one of [CC-01] to [CC-07]
that corresponds to the output terminal and output the signal.
Assign 084 [AC0] to 087 [AC3] to the output terminal functions [CC-01] to [CC-07].
The 4-bit output mode is selected when 087 [AC3] is assigned to the output terminal function, whereas
the 3-bit output mode is selected when it is not assigned.
The table below shows the alarm codes to be output.
Precautions for Correct Use
• The output state switches depending on whether 087 [AC3] has been set to [CC-01] to
[CC-07]. The 4-bit output mode is selected when 087 [AC3] has been set, and the signals
084 [AC0], 085 [AC1], 086 [AC2], and 087[AC3] will be output in accordance with the table
below even when all of them have not been set.
• The signals will be output in the 3-bit mode when one of or any pair from 084 [AC0], 085
[AC1], and 086 [AC2] have been set. The signals 084 [AC0], 085 [AC1], and 086 [AC2] will
be output in accordance with the table below even when all of them have not been set.
