Technical Specifications Model: NTAC‑02 Part Number: 58976008 Encoder Signal Type: Incremental encoder A/B/Z phase differential signal Maximum Pulse Frequency: 300 kHz Encoder Power Supply Output: 5 VDC / 24 VDC configurable Communication Interface: DDCS optical fiber interface Power Supply: 24 VDC ±10 % external power input Mounting Mode: 35 mm DIN‑rail mounting Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Receives differential A/B/Z incremental encoder signals for motor speed and position measurement. Configurable 5 VDC or 24 VDC power supply output for field encoder device. Signal hardware filtering suppresses pulse interference from industrial site. DDCS optical fiber bus transmits speed feedback data to drive main control unit. Front‑panel LED indicators show power‑on status, pulse signal receiving and DDCS communication status. Hardware fault detection monitors encoder signal loss and communication link failure.
Application Scenarios Spare‑part replacement for NTAC‑02 58976008 encoder interface unit of ACS600 drive system. High‑precision closed‑loop speed control for motors equipped with incremental encoder in metallurgy, paper‑making and lifting equipment. Retrofit of speed feedback channel for existing ACS600 variable‑frequency drive.
Working Principle NTAC‑02 is powered by external 24 VDC power source. It supplies working power to field incremental encoder according to configured voltage level. A/B/Z phase pulse signals from encoder enter module through terminal blocks, pass through filtering and conditioning circuit. Logic chip completes phase discrimination and pulse counting, calculates motor speed and position value.
Installation Requirements Clip NTAC‑02 onto standard 35 mm DIN‑rail inside drive cabinet and keep horizontal installation. Complete 24 VDC power‑supply wiring to power terminal block. Connect encoder shielded cable to signal terminals and set encoder output power voltage via hardware configuration.
