Main Programming Modes and Methods in PacScript
Online, Offline, Freedrive, and More
Programming DENSO robots in PacScript can be carried out in several modes, from editing directly on the operator panel to advanced simulation environments. At NexaRob, we help select the right method so that code deployment and maintenance are fast, safe and tailored to your team's needs. Below are the key modes:
Teach Pendant (Online Programming)
- Direct editing: Using a teach pendant, the operator can define trajectories and motion sequences that are immediately saved in PacScript code.
- Quick Corrections on the Line: Ideal for minor changes without requiring lengthy production downtime.
- Limitations: For more complex applications involving many points or advanced logic, this requires caution and is more time-consuming than working in an offline environment.
Offline Programming (Simulation Environment)
- Working on a computer: PacScript code and trajectories can be created in simulation software such as DENSO WinCAPS and then uploaded to the robot.
- Time savings: Production does not need to stop while a new version of the code is being prepared, minimizing downtime.
- Application: Complex applications or highly automated lines where every mistake generates significant costs
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 DENSO robot over the network and make changes to PacScript code without being physically present at the workstation.
- Expert support: Enables rapid problem solving without the need to send an engineer into the field.
Hybrid Approach
- Combining methods: Teach Pendant is usually combined with simulation software, using the pendant for simple corrections or initial calibration and simulation tools for optimizing more complex trajectories and processes.
- Continuous improvement: Once written, code can be improved iteratively in an offline environment, with final adjustments introduced online on robots already operating on the line.
PacScript Programming Methods are versatile and often combined depending on the specifics of production and the dynamics of process changes. This makes it possible to improve work DENSO robots in both simple and highly complex applications. In the following sections, we explain how these robots can work with vision systems or sensors to gain greater flexibility and safety.
Discover How DENSO Robots Can Use Cameras and Sensors to Respond Dynamically to Changing Production-Line Conditions
Integration with Vision Systems and Sensors in PacScript
DENSO robots programmed in PacScript are not limited to static, predefined motion paths. Through integration with vision systems and sensors, such as force, torque, or presence sensors, they can actively adapt their tasks to the current workstation situation. Below, we show how PacScript supports this flexibility:
Vision Systems
- Protocols and libraries: DENSO provides communication tools that enable data from 2D/3D cameras to be transferred to the robot, while PacScript allows dynamic trajectory corrections.
- Application: Detecting the position of parts in loosely scattered batches, visual quality control and sorting products by shape.
Force and Torque Sensors
- Precision Assembly: In delicate component-assembly applications, the robot can monitor pressing force to avoid damaging sensitive parts.
- Collision Detection: When a sensor exceeds a defined threshold, PacScript can immediately stop motion and trigger emergency procedures, preventing more serious damage.
Control of Additional Axes and Peripherals
- Greater flexibility: DENSO robots can share control with additional axes, such as rotary tables, while PacScript synchronizes their operation, which is particularly useful in multi-sided machining or welding components with difficult shapes.
- Unified platform: Communication with other industrial controllers and PLC systems is also possible, providing a consistent automation environment.
Application Examples
Food Industry
The robot recognizes fruit size using a camera and adjusts its grip to place fruit gently into packaging.
Electronics
Precise insertion of modules into motherboards, where a force sensor ensures correct pressure without the risk of breaking a pin.
Logistics
Sorting parcels by visually recognized barcodes; PacScript calculates the offset on the fly so the robot places shipments in the correct location.
PacScript Integration with vision systems and sensors allows DENSO robots adapt to unexpected deviations and respond to current conditions on the line. NexaRob supports the entire process, from designing vision and sensor infrastructure, through writing and optimizing code, to full implementation and personnel training. As a result, your line becomes more flexible, efficient, and ready for the challenges of modern production.

Case Study: Precision Assembly Automation with DENSO Robots and PacScript
Below we present an implementation example in the electronics sector in which DENSO robots, controlled using PacScript, significantly accelerated and improved the quality of the assembly process. Especially in applications requiring high accuracy, precise motion control and dynamic response to small deviations are key to success.
Context and Key Challenges
- Delicate components: Even slight pressure could damage sensitive components, leading to costly losses.
- Tight dimensional tolerances: Components had to be inserted with accuracy down to fractions of a millimeter so that the final product would meet strict quality standards.
- Frequent Variant Changes: Production included different device series, requiring rapid switching to new assembly sequences.
Solutions in PacScript Code
Application of Dynamic Force Control
The robot monitored pressure levels in real time in cooperation with a force sensor, adjusting speed and contact force to avoid damaging components. Exceeding the defined threshold immediately triggered emergency procedures, preventing cracks or deformation of the workpiece.
Modular Structure of Assembly Code
Each operation, such as tightening screws, connecting fittings, or positioning seals, had its own procedure in PacScript, making changes easier for subsequent product series. Parameters such as insertion depth or movement speed were described in a separate configuration file, speeding adaptation to a new product range.
Vision Verification
The camera checked the correct placement of the component before and after assembly. If a deviation occurred, PacScript corrected the trajectory or notified the operator that manual inspection was required. As a result, the number of defective components released to subsequent line stages fell significantly.
Results and Benefits
- Reduced Number of Rejected Parts: Thanks to precise force control and vision verification, the number of damaged or incorrectly assembled components decreased by approximately 30%.
- Increased efficiency: Smooth adaptation of the robot to new device models, combined with shorter cycle times, resulted in up to a 20 percent improvement in production pace.
- Ease of Code Modification: A modular approach and separate parameter configuration enabled rapid process changes when introducing new product ranges.
Thanks to the capabilities of PacScript - including force control and dynamic vision verification - rDENSO robots successfully met the requirements of the electronics industry, improving assembly quality and efficiency. NexaRob supported the investor at every stage, from process analysis through implementation and testing to operator training, helping ensure a stable and scalable production system.
