2. Product Overview

The NexBot Safety LA013-008 is a powerful 6-axis articulated robot arm engineered for high-payload automation tasks in demanding industrial environments. This robot provides an exceptional combination of strength, reach, and precision, making it an ideal solution for applications that involve heavy lifting and complex manipulation over a large work area. At the core of the LA013-008's capabilities is its substantial 120 kg payload capacity. This allows the arm to handle heavy workpieces, large end-of-arm tooling, or multiple parts simultaneously, significantly increasing throughput in material handling and machine tending operations. Complementing this strength is an extensive horizontal reach of 2700 mm, which creates a large, versatile work envelope. This extended reach is critical for applications such as palletizing full layers of product, servicing large CNC machines, or performing operations across a wide conveyor system. Precision is not compromised for power. The LA013-008 robot arm delivers a position repeatability of ±0.05 mm, ensuring that tasks are performed consistently and accurately cycle after cycle. This level of precision is essential for applications like spot welding, sealing, dispensing, and large-component assembly where quality is paramount. The 6-axis design provides maximum flexibility, allowing the arm to approach workpieces from virtually any angle and maneuver around obstacles within a crowded production cell. Constructed from high-strength cast aluminum alloy and sealed to an IP67 rating, the LA013-008 is built to withstand harsh industrial conditions, including dust, debris, and high-pressure water jets. This durability minimizes downtime and reduces maintenance requirements, ensuring reliable operation. The robot is designed for straightforward integration with standard industrial control systems and is typically paired with a NexBot G4 series controller for seamless programming and operation. Its robust design makes it a reliable workhorse for a variety of heavy-duty applications, including automotive body shop operations, foundry work, and end-of-line packaging.

3. Getting Started

1. System Components Overview

The NXB-ROB-LA013-008 system consists of three main components: the LA013-008 6-axis robot arm, the NXC-500 series controller cabinet, and the NXP-20 teach pendant. Familiarize yourself with the location of the main power switch on the controller and the emergency stop buttons on both the controller and teach pendant.

2. Powering On the System

To power on the robot, first ensure the main disconnect on the controller cabinet is switched on. Then, turn the key switch on the operator panel to the ON position. The teach pendant will boot up, and after a brief self-test, the system will be ready for operation.

3. Understanding Operating Modes

The robot has three primary operating modes, selected by the key switch on the teach pendant: T1 (Teach 1), T2 (Teach 2), and AUTO (Automatic). T1 is a slow-speed manual mode for programming, T2 allows for faster testing, and AUTO is for full-speed production execution. All programming and manual movement must be done in T1 mode with a deadman switch enabled.

4. Operation

Manual Jogging

Manual robot movement, or jogging, is performed using the teach pendant. You can select different coordinate systems, such as JOINT for individual axis movement, or WORLD/TOOL for linear movement relative to a fixed frame or the end-effector. Always use slow speeds when jogging near obstacles.

Tip: For large re-positioning moves, use the JOINT coordinate system. For precise linear alignment with fixtures, use the TOOL coordinate system after defining an accurate TCP.

Defining a Tool Center Point (TCP)

The TCP is the focal point of your end-of-arm tooling. Accurately defining the TCP's position and orientation relative to the robot's flange is critical for program accuracy. Use the built-in 4-point or 6-point teaching utility to define a new TCP whenever tooling is changed.

Setting Payload Data

To ensure optimal performance and prevent excessive wear, you must configure the payload data for the attached tooling and workpiece. Enter the mass (up to 120 kg), center of gravity, and moments of inertia in the payload settings screen. The system uses this data to optimize motor torque and motion profiles.

Tip: Always use a payload schedule that is slightly higher than the actual weight to provide a safety margin, but avoid excessively high values which can make motion sluggish.

Executing Production Programs

To run a program in automatic mode, select the desired program from the teach pendant, switch the mode to AUTO, and ensure all safety gates are closed. From the operator panel or PLC interface, initiate the cycle start command. The robot will then execute the program at full production speed.

5. Maintenance Schedule

IntervalTaskNotes
DailyVisually inspect the robot arm, cables, and controller for any signs of damage, fluid leaks, or loose connections. Confirm the work area is free of debris.This check should be performed by the operator at the start of each shift.
WeeklyTest all Emergency Stop buttons and safety interlocks (e.g., light curtains, door switches) to ensure they correctly halt robot motion.Log the results of each safety check.
MonthlyClean the exterior surfaces of the robot arm and controller cabinet. Check controller cabinet ventilation fans and filters and clean or replace as needed.Use only approved cleaning agents that do not damage the robot's IP67-rated seals.
QuarterlyInspect all robot cabling, especially at flex points, for signs of abrasion, cracking, or wear. Check the tightness of the robot base mounting bolts.Power down and lock out the robot before performing this check.
AnnuallyReplace the batteries for the absolute encoder backup in the robot base and the memory backup in the controller.Failure to replace batteries can result in the loss of mastering data and system parameters.
Every 10,000 HoursPerform a comprehensive lubrication service. Re-grease all 6 axis gearboxes using the specified lubricant and procedure.Refer to the service manual for specific grease types and quantities for each axis.

6. Troubleshooting

SymptomPossible CauseSolution
Robot stops with 'Position Following Error' or 'Motion Supervisor' alarm.The robot's actual position deviates too far from its commanded position. This can be caused by a collision, incorrect payload settings, or binding mechanics.Check the work envelope for obstructions. Verify that the configured payload data accurately reflects the current tooling and workpiece. Manually jog the axis to check for any mechanical resistance.
Teach pendant screen is blank or unresponsive.The teach pendant cable is disconnected or damaged, or the controller is not fully powered on.Ensure the teach pendant cable is securely connected at both the pendant and the controller. Inspect the cable for damage. Cycle power to the robot controller.
Programmed points are not reached accurately, affecting repeatability.The Tool Center Point (TCP) is defined incorrectly, the robot base is loose, or an axis requires re-mastering.Re-run the TCP definition procedure. Verify the torque on the robot's M24 base mounting bolts. Run the mastering check routine and re-master if necessary.
Robot will not move in manual mode.An emergency stop is active, a safety fence is open, the deadman switch is not engaged, or the motors are not enabled.Check and reset all E-stops. Ensure all safety gates are closed. Firmly press the deadman switch on the teach pendant and press the 'Motors On' button.
'EtherCAT Communication Fault' alarm is displayed.A network cable is unplugged or damaged, the master controller is offline, or there is a network configuration error.Inspect all EtherCAT cables for secure connections and damage. Verify the status of the master PLC or controller. Check network diagnostics for configuration issues.
An axis motor shows an 'Over Temperature' alarm.The robot is running a cycle that exceeds its duty cycle rating, the payload is set too low, or ambient temperature is too high.Reduce the speed or duration of the motion cycle. Verify payload settings are correct for the application. Ensure proper ventilation around the robot and controller.
Robot loses its home position (mastering) after a power outage.The absolute encoder backup batteries are dead or failing.Power down and lock out the system. Replace the batteries located in the robot base. After replacement, the robot will need to be re-mastered.
