Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
ABB NTAC-02 is a Pulse Encoder Interface Module designed for ABB ACS 600 frequency converters. The module provides an interface for digital pulse encoder connection when accurate speed or position feedback from the motor shaft is required.
The NTAC-02 Pulse Encoder Interface Module connects to the ACS 600 drive through an optical DDCS-protocol communication link. The module is typically connected with other optional modules on Channel CH1 of the NAMC Application and Motor Control Board, where the NAMC board operates as the communication master. :contentReference[oaicite:0]{index=0}
The ABB NTAC-02 supports encoder feedback applications for ACS 600 Standard Application Program, System Application Program, Crane Drive Application Program, and Application Program Template environments. :contentReference[oaicite:1]{index=1}
