FAQ

Q1: What is ABB NAMC-04?
A: NAMC-04 is an Application and Motor Control Board used in ABB ACS 600-series drive systems.

Q2: What is the main function of NAMC-04?
A: It performs the main application processing and motor-control functions of the ABB drive.

Q3: Which ABB drives use NAMC-04?
A: It is associated with the ACS 600 / ACx 600 family of ABB frequency converters. ABB documentation explicitly refers to software for NAMC-03/04 control boards.

Q4: Is NAMC-04 a PLC module?
A: No. It is a dedicated ABB drive control board, not a general-purpose PLC CPU or I/O module.

Q5: Does NAMC-04 support DDCS communication?
A: Yes. ABB documentation identifies the DDCS optical communication channel as compatible with NAMC-03/04/11 boards.
