Nidec Commander CDE 550 Simulator

Software simulator for the Nidec Commander CDE 550 inverter with a graphical interface, developed in Python with PyQt6.

What’s New in Version 0.0.2

• Complete localization of the user interface in Italian
• Improved alarm handling with reduced false positives
• Performance optimizations during startup and load variations
• Updated documentation with detailed CHANGELOG

Features

• Realistic simulation of Nidec Commander CDE 550 inverter behavior
• Intuitive graphical interface with PyQt6 fully localized in Italian
• Serial communication via pyserial
• Support for main control commands
• Fault and alarm simulation with advanced management
• Real-time parameter monitoring
• Event and error logging

Prerequisites

• Python 3.8 or higher
• Pip (Python package manager)
• Python virtual environment (recommended)

Installation

1. Clone the repository:

   git clone https://github.com/Nsfr750/CDE550-sim.git
   cd CDE550-sim
   

2. Create and activate a virtual environment (optional but recommended):

   # On Windows
   python -m venv venv
   .\venv\Scripts\activate
      
   # On macOS/Linux
   python3 -m venv venv
   source venv/bin/activate
   

3. Install dependencies:

   pip install -r requirements.txt
   

Usage

1. Start the simulator:

   python main.py
   

2. The graphical interface will show:
   • Inverter status
   • Operating parameters
   • Event log
   • Simulation controls
3. For serial connection:
   • Go to Connection -> Connect
   • Select the desired COM port
   • Set the communication speed (baud rate)
   • Click “Connect”

Supported Serial Commands
