NAIO Module The NAIO (Analogue I/O Extension Module) is an optional device for ACS 600 frequency converters. The module offers two current or voltage inputs and two current outputs. NAMC Board The NAMC is the Application and Motor Control Board of the ACS 600. There are different types of NAMC, e.g. NAMC-03 and NAMC-11. NDCO Board The NDCO (DDCS Communication Option) series includes optional communication boards for installation on top of the NAMC-11. NDIO Module The NDIO (Digital I/O Extension Module) is an optional device for ACS 600 frequency converters. The module offers two digital inputs and two relay outputs. NIOC Board The NIOC is the standard I/O interface of the ACS 600. It connects the drive to the external control circuits. NTAC Module The NTAC (Pulse Encoder Interface Module) is an optional device for ACS 600 frequency converters. The module offers an interface for a digital pulse encoder connection.

Overview

This chapter contains a description of the I/O Extension Link, the Pulse Encoder Interface Module, the I/O Extension Modules, and information on warranty

The I/O Extension Link

All the Pulse Encoder Interface Module (NTAC) and I/O Extension Modules (NDIO and NAIO) are connected to the frequency converter via an optical DDCS-protocol communication link. The modules, together with the NIOC Standard I/O Board, are usually connected in a ring on Channel CH1 of the NAMC (Application and Motor Control Board). The NAMC board acts as the master, polling the other stations cyclically. The modules respond to the master’s enquiries. Each device on the DDCS link has an individual node number. The modules are numbered by setting the DIP switches located inside the module enclosure. (The address of the NIOC board is fixed to 1.)

NTAC-02 Pulse Encoder Interface Module

The Pulse Encoder Interface Module (NTAC) offers an interface for a digital pulse encoder connection. A pulse encoder should be used if accurate speed or position (angle) feedback from the motor shaft is required.

Delivery Check

The package contains:

• NTAC-02 module 

• three pairs of fibre optic cables (120/370/2000 mm) 

• two jumper bridges (for encoder voltage selection) 

• mounting rail (DIN 50022, 35 × 7.5 mm, length 45 mm) 

•This manual, the NTAC-0x/NDIO-0x/NAIO-0x Installation and Start-up Guide.

Compatibility

The NTAC-02 is compatible with the following application programs: 

• ACS 600 Standard Application Program version 5.0 or later 

• ACS 600 System Application Program version 4.2 or later 

• ACS 600 Crane Drive Application Program version 5.0 or later 

• ACS 600 Application Program Template (all versions).

Encoder Recommendation

Leine & Linde 18690010, Hübner POG 10 or equivalent: • 90° (electrical) phase shift between channels 1 and 2 • Recommended output sinking/sourcing capability: 40 mA.
