More Information

Overview Manuals Board Role Frame & Phase Fit Installation Context Product Applications

Features:

  • Board role: Control distribution board used in an ACN/ACW644 +V991 phase-module conversion.
  • Frame scope: ABB maps NXPP-02C to R10i and R11i constructions.
  • Repair context: Supports conversion of a supplied V-phase spare for U- or W-phase service.
NXPP-02C belongs to a defined phase-module repair sequence rather than a standalone control-system I/O function.

ABB separates the R10i/R11i board from the NXPP-03C arrangement documented for R12i hardware.

The board selection must be reviewed together with the phase position, base plate, spacers, NINT assembly and shield connections.

Apter Power supports the ABB NXPP-02C ACN/ACW644 +V991 Control Distribution Board through quotations, documentation and frame-matching guidance.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Control distribution: NXPP-02C is installed in the R10i/R11i control-board arrangement.
  • Conversion step: ABB identifies it when converting a delivered V-phase spare to U- or W-phase duty.
  • Assembly context: The procedure also handles the NINT subassembly, base plate and shielding hardware.
  • Functional boundary: It is not documented as a general-purpose PLC, I/O or communication board.
  • R10i/R11i: Replace the documented NINT-72C arrangement with NXPP-02C.
  • R12i: ABB maps the larger frame to NXPP-03C, not NXPP-02C.
  • V-phase spare: A spare supplied for V-phase service does not require the included NXPP board until converted for U/W use.
  • Phase identification: Confirm U, V or W duty before releasing the repair kit.
  • Spacer change: ABB requires the documented metal-to-insulating spacer replacement during U/W conversion.
  • Reassembly: Refit the control assembly in the order shown in the official instruction.
  • Shield reference: Adjacent +V991 phase modules may require the specified shield busbar and base-plate connection.
  • Cable condition: Check flat-cable locking and fibre connectors, preserving a fibre bend radius above 35 mm.
  • Phase-module repair: Supports ABB ACN/ACW644 +V991 R10i/R11i service work.
  • U-phase conversion: Used when a V-phase spare is reconfigured for the documented U-phase position.
  • W-phase conversion: Used in the corresponding W-phase conversion with the required shield arrangement.
  • Exact-match sourcing: Frame size and phase-module construction must be known before ordering.
Description
NXPP-02C is a control distribution board identified in ABB’s ACN/ACW644 +V991 phase-module installation procedure. It is used for the R10i/R11i control-board arrangement when a supplied V-phase spare is converted for U- or W-phase service.

NXPP-02C is the R10i/R11i board in the documented mapping; ABB assigns NXPP-03C to R12i. The conversion also involves the NINT assembly, base plate, insulating spacer and shield-busbar arrangement described in the installation instruction.

NXPP-02C should therefore be sourced as part of an exact frame and phase-module repair plan, not as a general-purpose drive board. Before work begins, identify the frame size, phase position, +V991 construction and existing parallel-module arrangement.

Technical notes
ABB maps NXPP-02C to R10i/R11i and NXPP-03C to R12i in the ACN/ACW644 +V991 phase-module conversion. The +V991 and old phase-module constructions must not be paralleled in the same branch.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
A maintenance team has an R12i phase module; should it install NXPP-02C?
Use the documented NXPP-03C arrangement for R12i. ABB maps NXPP-02C to the R10i/R11i NINT-72C replacement path.
If a +V991 spare will remain in V-phase service, is NXPP-02C installed?
ABB states that the included NXPP board is not needed when the spare remains the V-phase module. Complete the applicable NINT jumper and wiring checks for the unchanged V-phase arrangement.
Why is fitting NXPP-02C alone insufficient when converting a +V991 spare to U- or W-phase duty?
The board change is one step in ABB’s conversion sequence. The NINT assembly, insulating spacer, reassembly order and current-adjustment jumpers must also follow the documented R10i/R11i procedure.
Can NXPP-02C be used in a branch that still parallels an old-construction phase module with +V991 hardware?
ABB prohibits parallel operation of old and +V991 phase-module constructions because it can cause serious IGBT failure. Upgrade the minimum number of parallel modules specified for the drive arrangement.
How does the number of adjacent +V991 phases affect shield hardware when installing NXPP-02C?
The base-plate and shield-busbar arrangement depends on which U, V and W phases use +V991 construction. Follow the matching ABB cabinet figure so adjacent control-board references remain connected as specified.
What fibre-cable condition should be protected during an NXPP-02C repair?
Keep the fibre bend radius above 35 mm and confirm the fibre connectors and flat-cable locks are secure before closing the phase module.
