1System Overview
NK300CX Integrated CNC System (Hereinafter referred as to NK300CX) consists
of hardware and software:
Hardware
•NK300CX host
•Operation panel and keypad panel
–NK300CX-H: WH106C operation panel and WH201C keypad panel
–NK300CX-V: WH108C operation panel
–NK300CX for Frilling: WH208A1 operation panel
•Lambda terminal board
It varies with axes configuration and software functions:
–Lambda 4S: pulse-type, up to 4 axes supported.
–Lambda 5S: pulse-type, up to 5 axes supported.
–Lambda 5E: pulse-type, up to 5 axes and absolute function supported.
–Lambda 5M: bus-type, up to 8 axes and absolute function supported.
•DB9M/F cables
See NK300CX Connection Diagram for how to connect all hardware.
Software
Based on an embedded platform, NK300CX software can be divided into the
following:
•Integral software: combine configurations of 3 axes, 4 axes, and 5 axes as a
whole.
•Multi-Z axes software: used for motion control of multi-Z axes, including
linkage configuration, double Y linkage configuration and alternative
configuration.
This section takes integral software under three-axis configuration as an
example.
See Main Software Interface for the introduction for its main software interface.
