Main Programming Modes and Methods in MELFA Basic
Online, Offline, Freedrive, and More
Programming Mitsubishi robots in MELFA Basic can be performed in several ways, from quickly creating code directly on the robot panel to advanced simulation tools operating outside the production environment. At NexaRob, we help select the right method for your needs and your team's capabilities so the entire code development and implementation process is fast, safe, and flexible. The main modes are presented below:
Teach Pendant (Online Programming)
- Direct control: The operator uses a Mitsubishi teach pendant to define the trajectory point by point and save sequences in MELFA Basic code.
- Quick Corrections on the Line: Ideal where small changes are required on the fly without prolonged process stoppages.
- Limitations: With complex operations, for example a large number of points or advanced algorithms, it can be more time-consuming and require greater care.
Offline Programming (Simulation Environment)
- Working on a computer: MELFA Basic code and motion trajectories are created in simulation software, such as RT ToolBox, before they are transferred to the actual production line.
- Time savings: The production line can keep running while engineers develop a new version of the code away from the shop floor. Uploading the finished program reduces downtime.
- Application: Large projects in which any error in robot movement could be costly or require lengthy corrections.
Remote Online Programming, Network-Based Control
- Remote access: If the network infrastructure is securely configured, the NexaRob team or your specialists can modify the code remotely.
- Expert support: Enables an immediate response to unusual errors or the need to optimize parameters without being physically present at the machine.
Hybrid Approach
- Combining methods: The process usually starts with the Teach Pendant to set base points, while the remaining sequence is optimized offline.
- Gradual improvement: Code written once can be improved by testing different variants in a simulator and then applying final adjustments online on the actual robot.
Programming methods in MELFA Basic are diverse. Several approaches are often combined and adapted to specific tasks and production dynamics. This flexibility can shorten implementation time while maintaining high precision and safety. In the following sections, we will show how integration with vision systems and sensors enables Mitsubishi robots to be even more "intelligent" and better adapted to your processes.

Integration with Vision Systems and Sensors in MELFA Basic
Mitsubishi robots programmed in MELFA Basic are not limited to simply repeating predefined sequences. By working with vision systems and force and torque sensors, they can dynamically adjust movement parameters, respond to unexpected obstacles, and maintain high precision under changing conditions.
Vision Systems
- Protocols and libraries: MELFA Basic supports communication functions with 2D and 3D cameras, allowing the robot to continuously correct its motion trajectory based on images from the surroundings.
- Application: Pick-and-place tasks with chaotically arranged parts, visual quality inspection or sorting goods by shape or size.
Force and Torque Sensor Handling
- Precision Assembly: In applications where a component must be fitted gently, the robot can limit force and speed based on sensor data.
- Collision Response: When the defined torque on an axis is exceeded, MELFA Basic can immediately stop motion and display an alert, protecting equipment and operators.
Additional Axes and Peripherals
- Expansion of workstations: The robot can control additional axes, such as rotary tables and positioners, increasing the reach and kinematic capabilities of the entire system.
- Unified platform: MELFA Basic helps maintain a consistent control environment, especially in facilities dominated by Mitsubishi automation.

Case Study: Using MELFA Basic in Precision Electronics Assembly
Below is an example implementation in the electronics industry where Mitsubishi robots controlled with MELFA Basic helped improve assembly precision and speed. With delicate components, accuracy matters, but so does skillful management of force and movement speed.
Context and Key Challenges
- Complex assembly processes: Many stages of assembling different subassemblies required meticulous precision and coordination.
- Low Tolerance for Errors: Even small deviations in component positioning could cause malfunction or require rework.
- Dynamic production: Frequent changes of product model or variant required rapid switching between motion sequences.
Solutions in MELFA Basic Code
Assembly Modules with Force Control
Individual activities, such as applying seals or soldering small pins, were divided into separate procedures in MELFA Basic. This gave each operation its own force and speed parameters, effectively protecting components from damage.
Integration with a Vision System
The camera verified the correct position of small parts and sent correction coordinates to the robot. MELFA Basic code continuously recalculated the motion offset, preventing incorrect assembly when a component was slightly displaced.
Dynamic adaptation to new product ranges
It was enough to add another set of parameters, such as soldering point positions and maximum contact force, to the existing procedures. Instead of rewriting the entire code, operators entered only the differences in configuration files, significantly reducing line changeover time.
Results and Benefits
- Fewer Defective Modules: Precise force control and visual verification reduced the percentage of damaged components in the assembly process.
- Increased Productivity: A smoother motion sequence and faster changeover to a new device variant improved the throughput of the entire line.
- Space Savings: The clever movements and compact design of Mitsubishi robots made it possible to use limited workstation space efficiently.
This example demonstrates that MELFA Basic performs very well in complex operations with low tolerance for error. NexaRob covered the entire project with support, from initial analysis and code development through commissioning and staff training, resulting in significant improvement of the assembly process and lower costs.

Code Optimization and Safety Procedures in MELFA Basic
After deploying MELFA Basic code, its operation should be continuously monitored and adjustments introduced to improve performance and workplace safety. NexaRob recommends a set of practices that support optimal operation of Mitsubishi robots:
Cycle Time and Trajectory Analysis
- Monitoring Statistics: The robot can report the number of cycles, the duration of individual operations, or the number of errors, making it easier to identify bottlenecks.
- Path optimization: Small reductions in movement distances and speed adjustments can significantly shorten cycle time while maintaining full safety.
Code Structure and Refactoring
- Modularity: Removing repeated sections by creating shared functions reduces the risk of errors appearing in multiple parts of the code.
- Clear Naming: Consistent and descriptive names for variables and procedures, such as pPickOffset and nMaxForce, accelerate project collaboration and make debugging easier.
Safety procedures and emergency systems
- Stop Conditions: MELFA Basic can respond to unexpected resistance or a collision by stopping movement immediately and activating a warning signal.
- Regular testing: We recommend periodically checking protective barriers and safety sensors and updating code to reflect new occupational safety regulations and standards.
Updates and extensions
- New firmware versions: Mitsubishi may provide fixes or additional functions. It is worth assessing whether an update will bring real benefits to your application.
