3. Getting Started

1. Power-Up Sequence

To begin operation, first ensure the main electrical disconnect is switched on. Then, turn the key or press the power button on the robot controller. The system will undergo a self-test and boot sequence, which may take up to 60 seconds.

2. Understanding the Teach Pendant

The teach pendant is the primary interface for controlling the robot. It allows you to switch between manual (T1) and automatic (AUTO) modes, jog the axes, create and edit programs, and monitor system status. Familiarize yourself with the enable switch, E-stop button, and coordinate system selection keys.

3. Homing the Robot

Before any programmed operation, the robot must be 'homed' or 'mastered' to establish a known reference position for all axes. This is typically done once after setup or if the robot loses its position. Follow the on-screen procedure on the teach pendant to perform the homing routine.

4. Loading a Program

Robot programs can be loaded from internal memory or a network location. Use the file navigation menu on the teach pendant to select the desired program and load it into the active memory. Always verify you have loaded the correct program for the intended task.

4. Operation

Manual Jogging (T1 Mode)

In T1 mode, you can move the robot manually using the joystick or axis keys on the teach pendant. This mode is used for teaching points, fine-tuning positions, and recovery. Movement speed is restricted for operator safety.

Tip: Use the 'JOINT' coordinate system for moving individual axes and the 'WORLD' or 'TOOL' coordinate system for linear movements.

Defining a Tool Center Point (TCP)

The TCP defines the focal point of your end-of-arm tooling. Accurately defining the TCP is critical for precise linear and orientation movements. Use the built-in TCP calibration wizard to define the X, Y, and Z offsets from the robot's J6 mounting flange.

Tip: For complex tools, define multiple TCPs. For example, a gripper might have one TCP at the center of the grip and another at a tip used for probing.

Creating a Basic Program

A program is a sequence of taught points and instructions. In T1 mode, move the robot to a desired position and record the point. Add instructions like 'grip', 'wait', or 'set output' between points to build a complete automation sequence.

Running in Automatic Mode

Automatic mode allows the robot to execute the loaded program at full speed. Before switching to AUTO, ensure all personnel have exited the safety cell, and all safety gates are closed. Select the program, reset any alarms, and initiate the cycle start from the PLC or operator panel.

Payload Configuration

To ensure optimal performance and longevity, you must configure the robot's payload settings to match the weight and center of gravity of your end-of-arm tooling and workpiece. The system uses this data to optimize motor dynamics and prevent excessive wear. This setting is found in the system configuration menu.

Tip: Update payload schedules in your program if the robot handles parts of different weights during its cycle.

5. Maintenance Schedule

IntervalTaskNotes
DailyVisually inspect the robot arm, cables, and controller for any signs of damage, leaks, or loose connections. Check the area for any new obstructions.This should be part of a pre-shift checklist for the operator.
WeeklyClean the robot arm and controller vents of dust and debris. Test the functionality of the teach pendant enable switch and E-stop button.Use only approved cleaning agents that will not damage seals or plastic components.
MonthlyCheck the tightness of the robot's mounting bolts and the end-of-arm tooling bolts. Listen for any unusual noise from the axis drive units during manual movement.Do not re-torque bolts unless they are found to be loose.
QuarterlyInspect the main umbilical and teach pendant cables for signs of abrasion, pinching, or wear. Verify the functionality of all safety interlocks and light curtains.Pay close attention to cable sections that flex repeatedly during operation.
AnnuallyReplace the grease in the J1 and J2 axis gearboxes as per the service manual. Check repeatability using a calibration fixture to detect any mechanical wear.This task should be performed by a NexBot-certified technician.
Every 3 YearsReplace the backup batteries inside the robot controller and at the base of the robot arm. These batteries maintain the encoder positions when main power is off.Failure to replace batteries will result in the loss of mastering data and require a full re-calibration.

6. Troubleshooting

SymptomPossible CauseSolution
Robot will not power on; no lights on controller.No incoming power or main breaker is tripped.Verify the main power disconnect is on. Check the facility circuit breaker. Use a multimeter to confirm 400-480VAC is present at the controller input terminals.
E-stop alarm is active and cannot be cleared.An E-stop button is pressed, or there is a fault in the safety circuit wiring.Check all E-stop buttons on the teach pendant, controller, and safety fence. If all are released, inspect safety circuit wiring for damage or loose connections.
Motion Fault' or 'Servo Lag' error on one axis.The axis is physically obstructed, the motor brake is stuck, or there is an issue with the motor drive.Check for any physical obstructions or collisions. Manually release the brake (with power off) to see if the axis moves freely. If the issue persists, contact NexBot support.
Robot position is not accurate (drifts over time).Robot mastering has been lost, TCP is incorrect, or there is mechanical looseness.Verify the TCP calibration. Check for any loose mounting bolts on the base or end-of-arm tooling. If the problem continues, the robot may need to be re-mastered.
PROFINET communication fault.Network cable is disconnected/damaged, IP address conflict, or incorrect device name.Check the physical network cable and its connection at the controller and network switch. Verify the robot's IP settings do not conflict with another device on the network. Ensure the device name matches the configuration in the PLC project.
Cannot switch to automatic mode.Safety gate is open, teach pendant is enabled, or a fault is active.Ensure all safety gates are closed and locked. Turn the key on the teach pendant to 'OFF' and disable the enable switch. Clear all active faults from the alarm screen.
Payload Overload' alarm.The robot is attempting to lift a weight exceeding the 120 kg limit, or the payload settings are configured incorrectly.Verify the weight of the part and tooling. Check the payload schedule settings in the robot configuration and ensure they accurately reflect the mass and center of gravity of the load.
