Software and Programming Guide

Development Environment and Tools

1. Core software components

Mint WorkBench: An integrated development environment (IDE) used for programming, debugging, parameter configuration, and motion monitoring, supporting Windows XP and above systems (32/64 bit). The main functions include:

Code editing and syntax checking

Real time data collection and graphical display (position, velocity, current, etc.)

Axis parameter configuration and servo tuning

Firmware Update and System Diagnosis

Mint Machine Center (MMC): Used for managing multi controller networks, supporting scanning and connecting multiple NextMove ESB-2 nodes, creating visual system layouts, and saving workspace configurations.

2. Software installation and connection

Installation requirements: The PC must meet the minimum configuration (1GHz processor, 512MB memory, 2GB hard disk space, USB or serial port), and administrator privileges are required for installation.

Connection method:

USB: Connect directly through USB Type B interface and automatically install drivers (compatible with Windows XP/Vista/7).

Serial port: RS232 (maximum 3m cable) or RS485 (supports multi machine cascading, requires terminal resistance matching).

Network: Connect distributed nodes through CANopen or Baldor CAN protocol.

Fundamentals of Mint Programming Language

Language characteristics

Mint is a structured language designed specifically for motion control, based on Basic syntax and extending motion control specific commands. Its features include:

Multi axis support: Control objects are distinguished by axis numbers (0-7), and multiple axes can be operated simultaneously.

Real time performance: The cycle time can be configured (1ms or 2ms) to ensure efficient execution of motion instructions.

Rich library functions: covering specialized commands such as point motion, speed control, synchronous following, etc
