ABB NISA-03 DDCS/ISA Adapter interface Board

Description

The NISA-03 is a specialized DDCS/ISA adapter interface board configured to enable direct control and monitoring of the ABB ACS 600 product family drives (also referred to as ACx 600) from a personal desktop computer. This electronic adapter board establishes a high-speed communication link that permits the execution of DriveWare PC software, such as DriveWindow, for drive commissioning, diagnostics, and parameter management. Operating over two distinct optical channels utilizing the proprietary DDCS protocol, the module provides a reliable fiber optic bridge to network-managed application and motor control boards.

Features

• Dual-Channel DDCS Processing: Equipped with one 5 megabaud optical channel and one 10 megabaud optical channel to accommodate varying terminal board connection speeds.
• PC Bus Integration: Occupies a single standard 16-bit ISA expansion slot on the desktop computer motherboard.
• Multi-Drive Architecture Support: Supports signal distribution to multiple individual frequency converters when paired with NDBU series branching units.

Applications

• DriveWare PC Software Communication: Interfaces standard office desktop PCs running DriveWindow software with industrial factory drive systems.
• ACS 600 Product Family Interfacing: Serves as the central fiber optic interface component to configure and monitor low-voltage motor drives.
• Distributed Drive Networking: Connects to NAMC control boards and NDBU branching nodes to form complex multi-drive automation arrays.

Installation Guidelines

• Electrostatic Precaution: Ensure an earthing wristband is worn during all handling phases, as the integrated circuits on the board are highly sensitive to electrostatic discharge (ESD).
• Address Configuration: Check the host PC configuration to ensure no existing interface card utilizes the default base address space of 280H. If a conflict occurs, adjust the onboard DIP switches (IAS0 to IAS2) to select the alternative 2A0H address profile.
• Card Insertion: Firmly and evenly press the adapter card into an available 16-bit ISA slot on the powered-down computer motherboard and secure the bracket with the retention screw.
• Fiber Optic Handling: Do not exceed the maximum long-term tensile load of 1 N or bend the fiber cables past the minimum short-term bend radius of 35 mm. Avoid touching bare fiber ends, and protect routing paths inside the drive using rubber grommets.
• Electrical Safety Warning: Never perform work inside the frequency converter while it is energized. Disconnect the main supply line and wait at least 5 minutes for the drive intermediate circuit capacitors to fully discharge before accessing the internal terminals.
