  • Use the NGDR board to amplify control pulses for the inverter IGBTs
  • Keep the gate-driver board associated with its documented phase-module power plate
  • Confirm the exact NGDR-07C suffix before treating the board as a service replacement
  • Receive main-circuit control commands through the documented NINT board path
  • Maintain the NGPS gate-driver supply arrangement used by the installed phase module
  • Preserve the two-NGDR-per-power-plate mapping documented for ACS 600 R4i–R7i frames
  • Localize the fault to the affected phase and power plate before changing NGDR-07C
  • Check the NINT command path, NGPS supply, connectors and earthing around the board
  • Test the associated IGBT and power plate when a power-stage fault remains after replacement
  • IGBT gate-drive control in ABB ACS 600 MultiDrive inverter phase modules
  • Control-pulse amplification on ACS 600 power plates in R4i and larger frames

Description
NGDR-07C is an ABB gate driver board identified by the supplied product label.

ABB defines NGDR as the NAC Gate Driver Board used in ACS 600 equipment to control inverter IGBTs and amplify control pulses received through the main-circuit control architecture.

Before replacement, confirm the exact host drive, power-plate position, board revision, NINT/NGPS connections and ABB parts-list compatibility; the NGDR designation alone does not prove that another suffix is interchangeable.

Technical notes
NGDR-07C is identified by the supplied product label; ABB documentation places NGDR boards in the ACS 600 IGBT control path. Confirm the host inverter, power-plate position and NINT/NGPS connections before replacement.

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.
What evidence should a buyer request before accepting an ABB NGDR-07C as a replacement?
Request a clear photograph showing the complete NGDR-07C marking and compare it with the removed board. Also verify the originating ACS 600 unit, power-plate location and original ABB parts list. ABB’s public manuals describe the NGDR board family but do not publish an NGDR-07C compatibility table.
Is ABB NGDR-07C the complete control board for an ACS 600 inverter?
No. ABB defines NGDR as the NAC Gate Driver Board that controls the inverter IGBTs. The NINT board provides the main-circuit control commands and measurement signals, while the NGPS supplies the gate-driver section; these are separate parts of the ACS 600 control architecture.
Can another NGDR suffix be substituted for ABB NGDR-07C because the connectors and PCB outline match?
No official equivalence should be assumed. ABB’s manuals refer to NGDR or NGDR-XX generically and do not identify other suffixes as replacements for NGDR-07C. Match the complete board marking and confirm the permitted part through the original drive’s parts list.
Does ABB documentation confirm that NGDR-07C fits every ACS 600 frame using NGDR boards?
No. ABB documents NGDR-family boards in ACS 600 MultiDrive frames from R4i upward and shows two NGDR boards controlling one power plate, but it does not assign the NGDR-07C suffix to every frame or board position. The host frame and power-plate parts list must therefore be checked separately.
Why can an ACS 600 fault remain after ABB NGDR-07C is replaced?
ABB’s fault-tracing material states that an earth-fault indication can originate in either an NGDR-family board or the associated IGBTs. Use the NINT indications to identify the affected phase or hottest power plate, then check the related NGDR connections and power plate before concluding that the replacement board is defective.
What safety checks are required before handling or measuring ABB NGDR-07C inside an ACS 600?
Disconnect the supply, wait at least five minutes and verify that the voltage between UDC+, UDC− and the frame is close to 0 V. ABB warns that converter control boards can remain at main-circuit potential and that external auxiliary supplies may leave other control voltages present.
Must both gate-driver boards on a power plate be replaced when one ABB NGDR-07C is suspected?
ABB shows two NGDR-family boards controlling one power plate, but its public manuals do not require automatic replacement as a pair and do not confirm that both positions always use NGDR-07C. Identify the faulty board and compare both complete markings with the original parts list before ordering replacements.
