ABB NTAC-02 provides the Pulse Encoder Interface Module function within ABB ACS 600 Drive Options installations.
- Conditions A and B quadrature encoder signals
- Accepts a once-per-revolution index channel
- Transfers feedback over the optical drive link
- Provides a selectable DDCS node identity
NTAC-02 operates with incremental pulse encoder, ACS 600 NAMC control board, DDCS optical fibers, 24 VDC control supply.
Typical engineered duties include Closed-loop motor speed control, Drive positioning feedback, Hoist and crane encoder systems, High-dynamic machinery drives.
Important Notice: NTAC-02 encoder voltage, A/B/Z polarity, node number and optical-ring position must match the ACS 600 configuration before closed-loop control is enabled.

Read the applicable ABB installation instructions before work. Verify NTAC-02 and the installed-system configuration.
1Place the motor and driven equipment in a controlled maintenance state.
2Confirm NTAC-02 and the assigned DIN-rail position.
3Isolate encoder and control supplies before terminal work.
4Select encoder supply and input logic levels as one coordinated setting.
5Set a unique DDCS node number before network start-up.
6Maintain A/B/Z phase order, shield continuity and optical-ring direction.
7Run at low speed and verify feedback direction and module diagnostics.
8Record node, wiring and feedback-test results before closed-loop release.
