SKU: NXB-GEN-221-019 | Version: 1.0 | Brand: NexBot Robotics
The NexBot Robotics 221-019 Teach Pendant is a robust, ergonomic human-machine interface (HMI) designed for the intuitive programming, setup, and manual operation of NexBot industrial and collaborative robots. This handheld pendant serves as the primary interface for technicians and operators, enabling direct control over robot movements, program creation, and system diagnostics right at the robot cell. Engineered for demanding industrial environments, the 221-019 features a bright, 10.1-inch full HD (1920x1200) capacitive touchscreen that provides a clear, detailed view of the programming environment and robot status. The responsive interface supports multi-touch gestures, allowing for efficient navigation and path editing, even while wearing standard work gloves. Its lightweight construction, weighing only 1.2 kg, and balanced ergonomic grip minimize operator fatigue during extended use. Safety is a core element of its design. The pendant is equipped with essential physical hardware controls, including a three-position enabling switch, a prominent emergency stop button meeting ISO 13850 standards, and customizable function keys. These tactile controls provide immediate, reliable access to critical safety and operational functions. The unit is sealed to an IP65 rating, making it dust-tight and resistant to low-pressure water jets from any direction, ensuring reliable performance in environments with dust, debris, or moisture. This pendant is an essential tool for a wide range of applications, including complex path programming for welding and dispensing, precise point teaching for pick-and-place and assembly tasks, and system configuration for material handling. Installation is straightforward, with a single, durable cable providing both power and communication through a quick-connect plug to the main robot control cabinet. This facilitates easy replacement and minimizes downtime during maintenance or in the event of damage.
Once connected to a powered robot controller, the teach pendant will boot automatically. The initial screen will display the NexBot Robotics interface, prompting for user login. Enter your assigned credentials to access the appropriate permission level.
The 10.1-inch touchscreen is the primary interface for all operations. Key areas include the top status bar (mode, alarms), the central viewport (program code, 3D robot model), and the bottom soft-key menu which changes based on the current context.
Use the dedicated mode key to switch between T1 (Manual, Reduced Speed), T2 (Manual, Full Speed - requires special authorization), and AUTO (Automatic Production). All programming and manual movements must be performed in T1 or T2 mode.
To enable robot servo power for manual jogging, the three-position enabling switch on the rear of the pendant must be squeezed and held in its center position. Releasing the switch or squeezing it fully will immediately disable servo power as a safety measure.
In T1 mode with the enabling switch engaged, select a coordinate system (e.g., Joint, World, Tool) from the jogging menu. Use the multi-axis joystick to move the robot along the selected axes. The speed can be adjusted using the on-screen override slider.
Navigate to the program editor to create a new routine. Move the robot to a target position and press 'Record Point' to add a motion instruction. You can modify instruction parameters like speed, termination type, and motion type by tapping on the line of code.
Accurate TCP configuration is critical for precise tool-oriented movements. Access the Tool Frame setup menu and use the guided, multi-point teaching wizard to define the position and orientation of your end-of-arm-tooling.
To ensure optimal performance and avoid excessive wear, declare the mass and center of gravity of your end-of-arm-tooling in the payload settings menu. The system uses this data to optimize the robot's dynamics and motor control.
Before running in automatic mode, always perform a test cycle in T1 mode. Use the 'Step' function to execute the program one line at a time, or run it continuously at a low speed override to verify the entire path is clear of collisions.
| Interval | Task | Notes |
|---|---|---|
| Daily | Inspect the pendant housing and cable for any visible damage, such as cracks, cuts, or abrasions. | Report any damage immediately. A compromised housing voids the IP65 rating. |
| Weekly | Wipe the 10.1-inch touchscreen with a soft, lint-free cloth and an approved electronics screen cleaner. | Do not use abrasive cleaners or solvents, which can damage the screen surface. |
| Monthly | Perform a functional test of the Emergency Stop button. Press to engage, verify the system stops, then twist to release. | The button should operate smoothly without sticking. |
| Monthly | Test the three-position enabling switch to ensure it functions correctly (off-on-off). | Verify that releasing the switch or squeezing it completely cuts servo power. |
| Quarterly | Inspect the multi-pin connector for bent or corroded pins. Ensure the locking ring threads are clean and undamaged. | Use a contact cleaner if minor oxidation is present. |
| Annually | Verify joystick and all button functionality in the controller's diagnostic input screen. | This check ensures all controls are registering correctly without intermittent behavior. |
| Symptom | Possible Cause | Solution |
|---|---|---|
| Pendant screen is blank or not powering on. | Loose cable connection, no power from controller, or internal pendant fault. | Ensure the robot controller is on. Disconnect and firmly reconnect the pendant cable at the controller. If the issue persists, test with a known-good pendant. |
| Touchscreen is not responding to touch. | Screen is dirty, calibration is lost, or a software freeze has occurred. | Clean the screen thoroughly. Power cycle the robot controller to reboot the pendant. If necessary, run the screen calibration routine from the system settings menu. |
| An 'Enabling Device Fault' is displayed. | The enabling switch is not being held in the correct middle position or the switch is faulty. | Ensure you are squeezing the switch only to its midpoint. If the fault continues, the switch may require service by a qualified technician. |
| Cannot jog the robot. | Not in manual mode (T1/T2), an E-Stop is active, or another safety fault is present. | Verify the mode is set to T1. Check that all E-Stop buttons are released and clear any active faults displayed on the pendant screen. Squeeze the enabling switch. |
| Pendant connection is intermittent. | The pendant cable is damaged or the connector is not fully secured. | Inspect the full length of the cable for damage. Ensure the connector's locking ring is fully tightened. Check for bent pins inside the connector. |
| Joystick movement is erratic or stuck on one axis. | Debris is obstructing the joystick mechanism or the joystick component has failed. | With the pendant disconnected, use low-pressure compressed air to clean around the base of the joystick. If the problem continues, the unit requires service. |
| Screen is difficult to read, appears dim. | Brightness setting is too low or the backlight is failing. | Navigate to the display settings menu and increase the brightness level. If the screen is still dim at the highest setting, contact NexBot Robotics support. |
