Pre-Installation Checklist

Before the robot even arrives at its designated work cell, thorough preparation is key. Rushing this stage can lead to delays, potential damage, or safety hazards.

Essential Checks

Visual Inspection

Upon receipt, immediately inspect the robot for any signs of shipping damage. Document anything unusual.

Lifting Capacity

Confirm that your available lifting equipment is rated well above the robot's weight (approx. 1300 kg, excluding DressPack and tooling).

Storage Conditions

If the robot won't be installed immediately, ensure storage environment meets temperature (-25°C to +55°C) and humidity (max 95%) limits.

Operating Environment

Verify the planned installation site's ambient temperature (+5°C to +50°C) and humidity (max 95%) align with requirements.

Protection Class

Verify the robot's protection type (Standard IP67 or Foundry Plus IP67) is suitable for the intended work environment.

Foundation Requirements

This is arguably one of the most critical checks before installation.

Loads

The foundation must withstand the static and dynamic forces and torques specified in the manual.

Levelness & Flatness

The foundation must be extremely level (max deviation 0.2 mm across attachment points) and flat (max tilt 0°).

Resonance Frequency

The minimum resonance frequency must be 22 Hz to avoid operational issues.

Pro Tip: Verify foundation levelness and cure time before the robot is delivered. Rectifying foundation issues with the robot present is significantly harder.

Safe Handling and Transport

Tipping Hazard Warning

An unsecured IRB 6700 is mechanically unstable. Its center of gravity shifts significantly with arm movements. Never attempt to move the robot arms before it is securely bolted to the foundation. Keep the robot in its designated shipping position until ready for final placement.

Approved Transport Methods

ABB strongly recommends Method 1: Transporting the robot without the tool attached, using appropriate lifting gear on the robot base.

If transporting with the tool attached is unavoidable (Method 2), it must be done using the specified transport support fixture, with the robot secured in the designated transport position for this setup.

Failure to use approved methods can damage the robot and void the warranty.

Recommended Transport Method
Method 1 (Tool Removed) is the preferred transport approach.

Lifting and Positioning

Once ready for final placement, use one of the approved lifting methods:

Forklift Lifting

  • Requires the optional Fork Lift Device Set (Art. No. 3HAC047054-002).
  • Four pockets must be securely bolted to the robot base (M20x60, 8.8 grade, 280 Nm torque). Never lift with fewer than four pockets.
  • Ensure the robot is in its shipping position and no extra load is attached.
  • Lift and move slowly and carefully. Crucially, no personnel should ever be under the suspended load.
Fork Lift Device Attachment
Section 2.4.1 details the mandatory fork lift device set.

Roundsling Lifting

  • Requires specific robot positioning (Axis 1: 0°, Axis 2: -45°, Axis 3: +65°, Axis 5: +70°). Brakes may need to be manually released to achieve this.
  • Uses four M20 lifting eyes (Working Load Limit: 2000 kg each) screwed into the base.
  • Requires specific lengths and arrangement of roundslings (4x 2.5m, 1x 2m, plus one securing sling).
  • Critical Safety: Ensure slings don't rub against sharp edges. The front securing sling must not be strained during the lift; it's for stability only.
Roundsling Attachment Configuration
Section 2.4.4 shows the specific sling arrangement.

Securing the Foundation

A rigid, stable connection to the foundation is essential for the robot's accuracy and lifespan.

Using a Base Plate (Optional but Recommended)

  • Simplifies leveling on uneven surfaces.
  • The base plate (Art. No. 3HAC12937-7, approx. 353 kg) is lifted using three M16 lifting eyes and secured to the foundation first.
  • Use leveling bolts and shims as needed to ensure the plate contact surfaces are perfectly level (max 0.2mm deviation).
  • Recommended anchor bolts (e.g., Hilti HDA-P M20) and concrete quality (C25/C30) are specified.

Securing the Robot

  • Lift the robot using one of the methods above.
  • Align the robot base with the foundation holes (or base plate holes). Use guide sleeves for precision. Gently lower the robot onto the guides.
  • Use four M24 x 100, quality 8.8 bolts with 4mm flat washers.
  • Lightly lubricate the bolts before assembly.
  • Tighten bolts to 625 Nm in a criss-cross pattern to ensure even clamping and prevent base distortion.
Robot Base Hole Configuration
Section 2.4.6 shows the M24 mounting holes.

Beyond the Manual - Pro Tips for Installation

  • Foundation First: Verify foundation levelness and cure time before the robot is delivered. Rectifying foundation issues with the robot present is significantly harder.
  • Lifting Gear Check: Always double-check the load ratings and condition of all lifting accessories (slings, shackles, eyes, crane/forklift) before every lift.
  • Protection Types Matter: Understand the difference. Foundry Plus (IP67) offers better resistance to fluids, dust, and heat compared to the Standard IP67, making it suitable for environments like die-casting or machining.
  • Cable Care from Day 1: As you position the robot, think about cable routing. Avoid sharp bends, pinch points, or excessive strain, especially for the main robot power (R1.MP) and signal (R1.SMB) cables.
  • Torque Wrench Accuracy: Use a calibrated torque wrench for securing foundation bolts. Incorrect torque compromises stability and safety.

Post-Installation Essentials

You've successfully unboxed, transported, and securely mounted your ABB IRB 6700. The physical foundation is set, but the journey to optimized and safe operation has just begun. Before you start programming complex tasks, several critical configuration steps and initial checks must be addressed.

Defining the Load: Accuracy, Performance, and Safety

Why is Correct Load Definition Crucial?

Accuracy & Path Performance

The robot's control system uses load data to calculate the dynamics required for precise movement. Incorrect data leads to path deviations, overshoots, and vibrations.

Component Lifespan

Overloading or operating with poorly defined inertia puts excessive stress on motors, gears, and the robot structure, leading to premature wear.

Cycle Time Optimization

With accurate load data, the robot can achieve optimal acceleration and velocity profiles, maximizing throughput without compromising stability.

Safety

Incorrect load data can affect braking distances and stop times. In emergency stop scenarios, unexpected behavior could occur if the controller's understanding of the load dynamics is flawed.

How to Define Loads

The detailed procedures for defining Tool Center Point (TCP) and payload data are found in the Operating manual - IRC5 with FlexPendant.

Key Parameters:
  • Mass (weight)
  • Center of Gravity (CoG) relative to the tool flange (axis 6 mounting face)
  • Mass Moments of Inertia around the CoG axes

Don't Guess: Use CAD data, physical measurements, or built-in load identification routines to determine these values accurately. Even small inaccuracies can have noticeable effects.

Permitted Extra Loads

The IRB 6700 allows for additional equipment to be mounted beyond the tool flange:

  • Upper Arm

    Up to 50 kg is permissible, provided its center of gravity is within 500 mm of the axis-3 extension centerline.

  • Frame (Hip Load)

    Equipment up to 250 kg can be mounted on the frame, but its total inertia (JHo + M4 x R²) must not exceed 100 kgm².

  • Tool Flange

    Be aware of the tool flange configuration on your specific robot (Standard Flange or LeanID Flange - Option 780-4).

Configuring the Working Range: Setting Safe Boundaries

While the IRB 6700 boasts a generous work envelope, it's often necessary to restrict its movement to prevent collisions with peripheral equipment, fixtures, or building structures, and to define safe zones for personnel.

Axes Restrictions

  • Axis 1 (Rotation): Can be restricted both mechanically (hardware stops) and via software parameters.
  • Axis 2 & 3 (Arm Motion): Restricted via software parameters only.
Axis 1 Mechanical Stop Example
Section 2.5.2 shows the mounting of an additional Axis 1 mechanical stop.

Mechanical Restriction of Axis 1

  • Purpose: Provides a physical barrier to prevent over-travel.
  • Method: Optional mechanical stop blocks (Art. No. 3HAC044287-001) can be added to the robot base. These offer adjustments in 15° increments between ±5° and ±125°.
  • Installation: Stops are bolted to the frame (M12x70, 12.9 grade, 115 Nm torque).

CRITICAL: Installing mechanical stops must be accompanied by corresponding adjustments to the software working range limits (Upper Joint Bound and Lower Joint Bound system parameters). Failure to update the software can lead to the robot unexpectedly hitting the mechanical stop under program control, causing potential damage.

Understanding Axis Ranges

  • Pay attention to the default working ranges versus the maximum possible ranges, especially for Axis 4 (Wrist) and Axis 6 (Turn). Axis 6, for instance, defaults to ±360° but can potentially achieve up to ±93.7 revolutions via software parameters (requires careful application review).
  • LeanID Impact: Robots with the LeanID option (780-4) have different default working ranges for Axis 5 (±120°) and Axis 6 (±220°) compared to the standard configuration. Furthermore, the allowed working area for Axis 6 is dependent on the position of Axis 5. This interdependence is crucial for path planning with LeanID.
LeanID Axis 5/6 Working Area
Section 2.2.2 details the specific working range relationship for LeanID.

First Power-Up: Safety, Synchronization, and Sanity Checks

Before the robot moves under program control for the first time:

  1. 1
    Re-Verify Safety

    Double-check that all safety circuits, E-stops, guarding, and interlocks are functional after all electrical connections have been made.

  2. 2
    Update Revolution Counters (Mandatory)

    This is the first crucial calibration step after installation or if the robot's position memory has been lost (e.g., due to SMB battery depletion, disconnection during transport, or certain errors).

    Why? The robot needs to know the exact "turn" each axis motor is on relative to its physical calibration marks (sync marks). Shipping vibrations or manual movement during installation can cause these counters to lose synchronization.
    Method: Manually jog each axis precisely to its calibration mark. Then, use the FlexPendant (ABB Menu > Calibration > Update Revolution Counters...) to store these positions.
    CRITICAL AXES (4 & 6): For some robot models, axes 4 and 6 have non-integer gear ratios. It's essential they are not just aligned by mark, but are on the correct revolution. If calibration seems off after updating, try rotating the affected axis by one full turn (360°) and updating again. Use the exact calibration values from the robot's label for confirmation.
    This is NOT Full Calibration: Updating revolution counters is a rough calibration. It does not establish the fine accuracy achieved by a full Standard Calibration (Calibration Pendulum) or Absolute Accuracy calibration (CalibWare), which should be performed later as needed.
  3. 3
    Check Calibration Position

    After updating the revolution counters, always verify the calibration position.

    • Use the FlexPendant Jogging window to command each axis to 0 degrees and visually check that the calibration marks align perfectly.
    • Alternatively, create a simple RAPID program with a MoveAbsJ[[0,0,0,0,0,0], ...] instruction and run it carefully in manual mode.

    If marks do not align perfectly after updating counters, DO NOT proceed. Re-check the manual jogging process and ensure the correct revolution was captured, especially for axes 4/6. Re-update the counters. Persistent issues may require a full standard calibration.

Maintaining Your ABB IRB 6700

Your ABB IRB 6700 is installed, configured, and likely performing demanding tasks. While robustly designed, like any sophisticated machinery, it requires regular, proactive maintenance to ensure peak performance, maximize its operational lifespan, and maintain safety standards.

This section focuses on the maintenance philosophy outlined in the Product Manual IRB 6700 (Document ID: 3HAC044266-001), highlighting key inspection, replacement, and lubrication tasks.

Understanding the Maintenance Schedule

Key Concepts

Maintenance Intervals

Intervals are defined based on:

  • Calendar Time: Specified in months (e.g., inspecting labels every 12 months), regardless of robot operation hours.
  • Operating Time: Specified in hours, tracked by the robot's Duty Time Counter (DTC). More intensive use means more frequent maintenance for these items.
Maintenance Categories

The schedule groups activities logically:

  • Cleaning: Regular removal of contaminants.
  • Inspection: Systematic checks for wear, damage, leaks, or incorrect levels.
  • Replacement/Changing: Scheduled replacement of consumables (oil, batteries) or components nearing end-of-life.
  • Lubrication: Applying grease/oil to specific components.
  • Overhaul: Major refurbishment typically performed after extended service life.

Preventative vs. Unpredictable: The schedule covers planned preventative maintenance. Any unexpected events, like collisions, error messages, or unusual noises, require immediate inspection and potential corrective action outside the regular schedule.

Critical Inspection Activities: Your Eyes on Robot Health

Regular inspections are the first line of defense against potential problems. Here are some of the most critical checks:

Gearbox Oil Levels

Why: Correct oil levels are vital for gear lubrication, heat dissipation, and preventing premature wear in all six axes.
How: Each axis gearbox has specific oil level plugs and required levels. Procedures often require the robot to be in its calibration position.
Frequency: Typically checked every 12 months.

Key Point: Use the correct procedure for each axis as level checking methods vary. Always ensure plugs are re-tightened to the specified torque (often 24 Nm). Refer to Technical reference manual - Lubrication in gearboxes (3HAC042927-001) for oil types.

Balancing Device

Why: This critical component (gas spring or mechanical spring unit) counterbalances the weight of the robot arm, reducing load on the Axis 2/3 motors. Failure can lead to motor overload or uncontrolled movement.
Inspection Points:
  • Dissonance: Listen for tapping (internal springs) or squeaking (piston rod/bearings).
  • Damage: Check the piston rod for scratches or wear.
  • Leakage: Inspect seals around the link ear for grease leakage.
  • Clearance: Ensure no debris obstructs its movement within the frame.
Frequency: Every 12 months.

Cable Harness

Why: The harness routes power and signals throughout the robot. Damage leads to communication errors or complete failure.
Inspection: Visually check the entire harness for wear, cuts, or abrasions. Pay special attention to areas with high flex, particularly around Axis 2 and 3. Feel inside protective tubes for chafing. Check connectors and securing brackets/straps.
Frequency: Dependent on usage (Duty Time Counter based) – check schedule. Replace immediately if damage is found or expected life is approached.
Cable Harness Wear Points
Focus inspection on harness flex points.

Mechanical Stops & Dampers

Why: These protect the robot from over-travel or absorb impact energy.
Inspection: Check for deformation, cracks, or significant impressions (>1mm on dampers) after any suspected collision or hard stop. Ensure mounting screws are tight and undamaged.
Frequency: Every 12 months or after an incident.

Scheduled Replacements & Fluid Changes

Replacing consumables and fluids at recommended intervals is crucial for preventing wear and ensuring continued operation.

Gearbox Oil Changes

Why: Oil degrades over time, losing lubricity and accumulating contaminants. Regular changes are essential for gearbox longevity.
Interval: Typically every 20,000 operating hours, but always verify with the specific maintenance schedule.
Key Points:
  • Correct Oil: Only use the specific oil type recommended for each gearbox axis in the documentation. Mixing oils can cause severe damage.
  • Procedure: Follow the draining and filling procedures precisely to ensure the correct amount is added and air is properly vented. Warming the robot/oil slightly before draining helps.
  • Safety First: Gearbox oil can be hot (up to 90°C) and potentially under pressure. Read and follow all safety warnings – use protective gear (goggles, gloves), open plugs carefully, and dispose of used oil correctly.

SMB Battery Replacement

Why: The Serial Measurement Board (SMB) battery powers the memory that stores the revolution counter data for each axis when the main controller power is off. A dead battery means lost synchronization and requires recalibration.
When: Replace immediately upon receiving the "Battery charge low" alert (Event Log message 38213) or at the scheduled interval (e.g., every 72 months – check schedule).
Best Practice: To avoid losing synchronization, keep the main controller powered on from the moment the low battery warning appears until the battery is replaced.
Procedure: Follow the replacement steps carefully. Remember ESD precautions. After replacement, an update of the revolution counters is mandatory if power was lost or if synchronization is suspect.

Essential Lubrication and Cleaning

Balancing Device Bearing Lubrication

Specific bearings within the balancing device require periodic greasing (e.g., front spherical roller bearing). Follow the manual for procedure and correct grease type (Optimol PD0 specified).

Frequency: Check schedule (e.g., every 72 months).

Robot Cleaning

Why: Accumulation of dirt, debris, or process residue can impede movement, cause overheating, or damage seals and cables.
Frequency: Highly dependent on the operating environment.
Allowed Methods:
  • Standard/Foundry Plus: Vacuum cleaner, wiping with mild detergent/spirit, low-pressure water rinse (rust inhibitor recommended, dry afterwards).
  • Foundry Plus Only: High-pressure water or steam (max pressures/temps specified, rust inhibitor essential, specific nozzle types and distances required).

CRITICAL Don'ts for Cleaning

  • Never spray water/steam directly at connectors, seals, gaskets, or joints.
  • Never use compressed air (can force debris into sensitive areas).
  • Never use unapproved solvents.
  • Maintain minimum spray distance (0.4m).
  • Ensure all protective covers are fitted before cleaning.

Planning for the Long Haul: Expected Component Life

Beyond scheduled maintenance, be aware that major components have an expected service life, heavily influenced by usage patterns ("normal" vs. "extreme" use cases are defined).

Component Normal Use Extreme Use Notes
Cable Harness ~40,000 hours ~20,000 hours Replace if damaged
Balancing Device ~40,000 hours - Based on specific test cycle
Gearboxes ~40,000 hours - With proper oil changes

Maintenance Investment

Regular, diligent maintenance based on the ABB schedule is not an expense; it's an investment in the continued productivity, reliability, safety, and longevity of your IRB 6700. By performing timely inspections, fluid changes, component replacements, and proper cleaning, you proactively address potential issues, prevent costly unplanned downtime, and ensure your robot operates at its best for its entire service life.
