Main Programming Modes and Methods in Yaskawa INFORM
Online, Offline, Freedrive, and More
Yaskawa robot programming in INFORM can be performed in several modes, from creating code directly on the robot panel to advanced solutions operating remotely or in simulation environments. At NexaRob, we help select the optimal method so application development and deployment are as fast, safe, and flexible as possible. The key modes are outlined below:
Teach Pendant (Online Programming)
- Direct editing: The operator uses the pendant to define movements point by point, saving them immediately in INFORM code.
- Quick Corrections on the Line: Ideal in situations where minor changes need to be made without interrupting operation for an extended period.
- Limitations: With more complex sequences, programming requires caution and is more time-consuming than working in an offline environment.
Offline Programming (Simulation Environment)
- Working on a computer: Creating and testing code in simulation tools, for example Yaskawa software (MotoSim), makes it possible to eliminate errors before deployment at the workstation.
- Time savings: The line can continue operating while engineers prepare the next version of the application. Once uploaded to the controller, only minor adjustments are required.
- Application: Large projects or processes with stringent safety requirements, where any mistake during live programming would be costly.
Remote Online Programming, Network-Based Control
- Remote access: If the network infrastructure is properly secured, the NexaRob team or your specialists can connect to a Yaskawa robot over the network and make changes to INFORM code.
- Expert support: Rapid resolution of unusual problems or performance improvements without the need to send an engineer on site.
Hybrid Approach
- Combining methods: Most often, a Teach Pendant is combined for initial calibration and establishing motion points with simulation software for optimizing trajectories and logic.
- Continuous improvement: Existing code can be iteratively improved by testing different variants in the simulator and then making final corrections online.
The programming method depends on the facility's specifics and how often the process changes. Several approaches are often used in parallel within one company: Teach Pendant for quick adjustments, offline for advanced optimization, and remote control for ongoing expert support. In the following sections, we will describe integration Yaskawa robots with vision systems and sensors, enabling even more intelligent automation.

Integration with Vision Systems and Sensors in INFORM
Yaskawa robots controlled with INFORM are not limited to reproducing predefined paths. They can also respond in real time to information from external devices such as cameras or force sensors. Below we show how such integration improves process efficiency and safety:
Vision Systems
- Protocols and libraries: Yaskawa provides tools for communication with 2D/3D cameras, allowing data on the position, size, or shape of objects to be transferred directly into INFORM code.
- Trajectory Correction: If products are arranged irregularly, the robot can calculate an offset and adapt its movement to the current position of the component, reducing pick & place operation time.
Force and Torque Sensors
- Pressure Control: In assembly applications or when handling delicate goods, the robot checks force levels to avoid damage.
- Collision Detection: When torque on an axis exceeds a defined value, INFORM can stop the robot and trigger emergency procedures, protecting equipment and operators.
Peripheral and Additional-Axis Control
- Extended capabilities: A single Yaskawa control unit often handles several axes, such as a rotary table, while INFORM code synchronizes their movement during complex welding or processing operations.
- Unified platform: With a consistent control environment (PLC, HMI, robot), the production process is easier to manage and expand.
Application Examples
Food Industry
The robot recognizes the position of irregularly shaped fruit and gently transfers it to the packaging conveyor.
Electronics
PCB assembly in which a vision system verifies the accuracy of microchip placement while a force sensor protects components from crushing.
Logistics
Sorting shipments based on size and barcodes, which the camera passes to the INFORM code, makes it possible to automatically route them to different warehouse sections.
Thanks to integration of INFORM code with vision systems and sensors, Yaskawa robots can respond intelligently to current production line conditions by adjusting positions, force, and motion sequences. NexaRob helps make full use of these functions, from equipment selection through code development and testing to training and service support, ensuring intelligent and safe automation.
A practical example showing how Yaskawa INFORM code improves key welding stages and raises quality in the demanding automotive industry
Case Study: Optimization of the Steel Component Welding Process in the Automotive Industry
In the automotive industry, where repeatability and perfect weld quality are essential, Yaskawa robots have been trusted by manufacturers for years. Below we present a case study showing how INFORM improved a complex welding process for steel components produced in high volumes:
Context and Key Challenges
- Complex part shapes: Multi-plane and multi-axis welds, often on curved surfaces.
- High repeatability: Even a small deviation in the weld seam could reduce component strength or require rework.
- Production Rate: Line efficiency could not be significantly reduced because of high volumes and short delivery deadlines.
Solutions in Yaskawa INFORM Code
Division of the Program into Welding Modules
Each part of the weld, such as horizontal, vertical or arc welding, had its own procedures, making it easier to modify parameters when requirements changed. Wire-feed speed and welding current could be adjusted on the fly thanks to the flexible code structure.
Use of Sensors and a Vision System
When the camera detected a slight deviation in the position of a component, INFORM calculated an offset for the motion trajectory to maintain seam accuracy. Force and torque sensors ensured welding tool stability, minimizing vibrations and accidental displacement.
Use of an Additional Axis, Positioner
For harder-to-reach welds, the robot used a rotary table controlled together with the arm. INFORM coordinated the simultaneous movement of both axes, maintaining the optimal welding torch angle throughout the entire cycle.
Results and Benefits
- Quality improvement of approximately 20%: Fewer defective welds and less frequent need for rework.
- Reduced cycle time: Precise trajectory control and the ability to make adjustments during the process helped accelerate the welding operation.
- Easy Adaptation to New Components: The modular code structure and parameterized welding settings enabled rapid switching to different components on the same line.
This case shows how Yaskawa INFORM can deliver measurable benefits in welding applications where both repeatability and flexibility matter. NexaRob supported the customer at every stage, from process analysis through code implementation and testing to staff training. As a result, the welding line achieved higher efficiency and quality while reducing rework costs.
