PRODUCT DESCRIPTION
NINT-73C Drive Interface Circuit Board
ABB NINT-73C is a circuit board in the control assembly of the documented R12i ACN/ACW644 drive module arrangement. NINT-73C is the interface board identified in the original assembly; the +V991 phase-module repair instruction describes its replacement with NXPP-03C in the specified U/W-phase conversion.
The R12i procedure identifies eight M4x8 base-plate fasteners and eight M4x20 spacers. The shield and insulating-spacer arrangement is part of the conversion, while the V-phase NINT current-setting jumpers S2 through S4 must match the power-plate rating. The R10i/R11i board combination is different and is not treated as interchangeable with the R12i pair.

SYSTEM INTEGRATION
Integrate NINT-73C within ACN/ACW644 +V991 R12i
Use NINT-73C only in the drive frame and assembly covered by the applicable ABB instructions. Figure 2 identifies the R12i NINT-73C/NXPP-03C combination separately from the R10i/R11i NINT-72C/NXPP-02C combination.
For the +V991 U/W-phase procedure, retain the R12i base plate, spacer locations and shield arrangement specified in the drawings. The conversion is a mechanical and control-assembly operation, not merely a plug-in substitution based on the printed board name.
Identify whether the V-phase is original or +V991 before planning the inter-phase reference connection. ABB provides different cabinet connection instructions for those cases and requires the applicable current-setting jumpers to be checked against the power-plate rating.
Features:
- Documented module frame: R12i
- U/W assembly base fasteners: 8 x M4x8
- ACN/ACW644 +V991 R12i
Use NINT-73C only within the documented ACN/ACW644 +V991 R12i arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace NINT-73C within ACN/ACW644 +V991 R12i
Photograph NINT-73C, the frame identification, phase position and board connections before removal. Distinguish an original-board spare from a +V991 phase-module conversion so that the replacement scope is not silently changed.
Follow the ABB isolation and discharge procedure for the complete drive before handling the assembly. Retain the insulating spacers and shield details from the R12i drawings, and do not transfer the smaller-frame fastener arrangement to this frame.
After the documented conversion or repair, inspect the inter-phase reference connection and the V-phase current-setting jumpers under the applicable ABB configuration instruction. Complete the drive-specific return-to-service checks before energizing the repaired assembly.
Features:
- NINT-73C complete suffix
- V-phase current-setting jumpers: S2 through S4; match power-plate rating
- R12i frame and U/W-phase conversion arrangement matched
Use NINT-73C only within the documented ACN/ACW644 +V991 R12i arrangement and applicable installation instructions.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about NINT-73C
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Which frame is associated with NINT-73C in the ABB conversion drawing?
The official +V991 instruction places NINT-73C in the R12i NINT-73C/NXPP-03C board combination, distinct from R10i/R11i. -
Is the NINT-73C conversion just a board-name substitution?
No. The documented procedure involving NINT-73C also addresses the base plate, insulating spacers, shield and inter-phase reference connections. -
How many base fasteners are shown for the R12i NINT-73C assembly?
The R12i assembly drawing associated with NINT-73C identifies eight M4x8 fasteners and eight M4x20 spacers. -
Can the R10i/R11i arrangement be copied to NINT-73C?
No. The ABB drawing distinguishes the R10i/R11i NINT-72C/NXPP-02C arrangement from the R12i combination containing NINT-73C. -
Which V-phase jumpers are checked during the NINT-73C repair?
ABB directs the V-phase NINT current-adjustment jumpers S2 through S4 to be checked against the power-plate rating during the repair arrangement involving NINT-73C. -
Why does the V-phase version matter when installing NINT-73C?
The cabinet reference-connection procedure involving NINT-73C differs depending on whether the V-phase is original or +V991; use the applicable ABB drawing. -
What should a distributor clarify about NINT-73C scope?
Clarify whether NINT-73C is requested as a bare board, an assembled spare or part of the +V991 conversion kit. These scopes are not established by the board name alone. -
Which identification photos help source NINT-73C?
Provide the complete NINT-73C marking, drive/frame nameplate, phase position and connector photographs, with required quantity and condition stated in the request.
