ABB NTAC-02 58976008

ABB NTAC-02 (Part No. 58976008) is a pulse encoder interface module designed specifically for ABB ACS800 series drives. Its primary function is to convert pulse signals from external encoders (ABZ or differential quadrature pulses) into digital position signals and speed feedback recognizable by the drive, enabling high-precision motor position and speed control.

Key Technical Specifications (Typical)

Power Supply: 15 V / 24 V DC (powered directly from the drive)

Power Consumption: Approx. 3 W, maximum current ≈ 300 mA

Input Signal: Differential quadrature pulse (ABZ), supporting an input range of 5–30 V DC

Maximum Input Frequency: Approx. 100 kHz

Resolution: Up to 4096 pulses per revolution (depending on encoder)

Dimensions: Compact module suitable for installation in ACS800 drives (approx. 75 mm × 108 mm × 45 mm)

Operating Temperature: –25 °C to +70 °C, with strong noise immunity

Typical Applications

Precise position closed-loop control in servo systems

Tension control, synchronization control, and other automation processes requiring high-speed position feedback

Robotics, machine tools, and other high-precision motion control equipment

In summary, ABB NTAC-02 (58976008) is a high-precision pulse encoder interface dedicated to ABB ACS800 drives, ideal for various industrial automation systems that require reliable position feedback.
