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?
Q
 Output terminals [11], [12], [AL0]-[AL1]/[AL0]-[AL2] are intelligent output terminals. By assigning
A
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.

Assigns output terminal functions to the output
terminals [11], [12], [AL0] to [AL1]/[AL0] to [AL2].
The settings of [C021], [C022], and [C026]
correspond to the output terminals, respectively.
Operates as "a" contact (NO).
Operates as "b" contact (NC).

of initial setting when [b085] is set to
other value, refer to "18.2.5 C Parameter
