9.16 Functions with External Signal Output
9.16.1 Using External I/O Output Signal Functions
 How to detect warning, error, and status signals emitted by the inverter with an external system?
 Output terminals [11], [12], [AL0]-[AL1]/[AL0]-[AL2] are intelligent output terminals. By assigning
the functions in the list of output terminal functions shown on the next page to [C021], [C022],
and [C026], the specified functions can be assigned to the corresponding output terminals.
 The output terminals [11], [12], [AL0]-[AL1]/[AL0]-[AL2] can be individually selected as "a"
contact (NO) input or "b" contact (NC) input by setting [C031], [C032], and [C036].
 The output terminals [11] and [12] are open collector outputs, and the output terminals [AL0]-
[AL1]/[AL0]-[AL2] are "c" contact relay outputs.
 When using a "c" contact relay, check the power supply status and the open/close status of the
relay output terminals.
