        More Information

        Overview Manuals Drive Compatibility Encoder Interface Commissioning Application
        • Pulse-encoder interface for supported ACS 600 speed and position feedback applications
        • A/B/Z inputs support single-ended or differential encoder signals up to 100 kHz
        • Uses a jumper-selected 15 or 24 V DC encoder supply and a DDCS link to NAMC channel CH1

        ABB NTAC-02 connects a digital pulse encoder to supported ACS 600 applications that require accurate motor-shaft speed or position feedback.

        Its quadrature inputs accept channels A and B with a 90-degree phase shift, while channel Z supplies one reference pulse per revolution for positioning.

        Selection and commissioning require compatible application software, a suitable encoder output stage, the correct supply jumper, a unique DDCS node address and cable length appropriate to the encoder output type.

        Availability, condition, price, and shipping time for ABB NTAC-02 are confirmed during quotation.

        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.

        • Use with ACS 600 application software versions explicitly listed in the ABB manual.
        • Standard Application 5.0 and later requires NTAC-02 rather than NTAC-01.
        • Confirm the installed NAMC channel and application program before replacement.
        • Use a digital pulse encoder with 90-degree channel displacement.
        • ABB recommends a push-pull output capable of 40 mA for the documented installations.
        • Confirm encoder supply, A/B/Z channels, cable shield, and terminal allocation before wiring.
        • Set an unused DDCS node address before energizing the interface.
        • Check the optical transmitter/receiver pair and fibre routing between NTAC-02 and NAMC.
        • Verify speed direction and feedback stability before returning the drive to normal control.
        • Closed-loop motor-speed feedback in supported ACS 600 drive applications
        • Position or shaft-angle feedback using quadrature A/B signals and the channel-Z reference pulse
        • ACS 600 master-follower systems that require pulse-encoder feedback on mechanically coupled shafts
        Description
        ABB NTAC-02 provides a digital pulse-encoder interface for supported ACS 600 applications requiring accurate shaft-speed or position feedback.

        It connects to NAMC channel CH1 through a DDCS optical link and accepts single-ended or differential A/B/Z encoder signals with a jumper-selected 15 or 24 V DC encoder supply.

        Before commissioning, verify application-software compatibility, encoder output type and frequency, cable length, node address, fibre pairing, shielding, feedback direction and drive parameter settings.

        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.
        VIEW ALL FAQS
        Which ACS 600 software versions can use ABB NTAC-02?
        Use only the application versions listed in the ABB manual: Standard Application 5.0 or later, System Application 4.2 or later, Crane Application 5.0 or later, and all Template Application versions; verify the actual drive software before ordering.
        What encoder output should be checked before selecting ABB NTAC-02?
        Confirm a digital quadrature encoder with 90-degree phase displacement and an output stage suitable for the documented interface. ABB recommends a push-pull output able to supply 40 mA in the stated arrangements.
        Can ABB NTAC-02 be treated as a direct replacement for NTAC-01?
        No. ABB states that NTAC-01 and NTAC-02 are not interchangeable in every application, and Standard Application 5.0 or later specifically requires NTAC-02. Check software, supply, wiring, and node configuration.
        How can ABB NTAC-02 receive its 24 V DC encoder supply?
        The official manual permits supply through the NIOC arrangement up to the documented current limit or from a suitable external source. Match the selected supply method to the encoder load and grounding plan.
        What causes a DDCS addressing conflict with ABB NTAC-02?
        A conflict occurs when two interfaces on the same NAMC channel use the same node address. Set the DIP switches before power-up and document the address used by each installed module.
        What should be inspected in the fibre connection for ABB NTAC-02?
        Confirm the correct transmitter-to-receiver pairing, clean connector ends, minimum bend radius, undamaged fibres, and the documented NAMC channel. Reversed or damaged fibres prevent valid feedback communication.
        How should ABB NTAC-02 feedback be checked after installation?
        With the drive in a controlled commissioning state, verify encoder direction, stable pulse feedback, expected speed scaling, status indication, and absence of DDCS or feedback faults before enabling normal operation.
