Introduction

This guide details the standard installation procedure for the NexBot Drives HA014-002 6-Axis Robot Arm (SKU: NXB-ROB-HA014-002). Proper installation is critical for ensuring the safety, performance, and longevity of the robot. This procedure covers site preparation, mechanical mounting, electrical connections, and initial verification. This robot is part of the R-100 series and is designed for heavy payload applications requiring high precision and repeatability.

Following these steps carefully will ensure the robot operates within its specified ±0.07 mm repeatability and meets all safety requirements. This procedure must be performed by qualified personnel familiar with heavy machinery and industrial electrical systems.

Safety Precautions

WARNING: Failure to observe safety precautions can result in serious injury, death, or damage to the equipment. Read the entire manual before proceeding.

• Crush Hazard: The robot arm weighs over 1500 kg. Use only certified and appropriately rated lifting equipment (e.g., overhead crane, gantry) for all handling and positioning tasks. Never stand under a suspended load.
• Electrical Hazard: The system operates on 480VAC 3-phase power. All electrical work must be performed by a qualified electrician. Always apply a Lock-out/Tag-out (LOTO) procedure to the main power disconnect before accessing electrical cabinets or connection points.
• Unexpected Motion: Before applying power, ensure the robot's work envelope is clear of all personnel and obstructions. Be prepared to activate the emergency stop (E-Stop) at the controller and teach pendant at all times during setup and testing.
• Personal Protective Equipment (PPE): Steel-toed boots, safety glasses, and gloves are required during the installation process.

Prerequisites

Site Preparation

1. Foundation: The mounting surface must be a reinforced concrete floor, level to within 1.5 mm over the robot base footprint. The foundation must be designed to withstand the robot's static weight and the dynamic loads generated during high-speed operation. Consult the official foundation requirements document for detailed specifications.
2. Clearance: Ensure adequate clearance around the robot's full 3,200 mm reach. Refer to the work envelope diagrams in the product manual. Allow sufficient space for maintenance access.
3. Power: A dedicated 480VAC, 3-phase power circuit with a lockable disconnect must be available near the robot controller location.

Tools and Equipment

• Overhead crane or forklift (rated for >2000 kg) with appropriate rigging.
• Torque wrench capable of measuring up to 800 Nm (590 ft-lbs).
• Precision leveling tool (laser or bubble level).
• Metric socket and wrench set.
• Lock-out/Tag-out (LOTO) kit.
• Multimeter.
• NexBot Drives Mounting Bolt Kit (NXB-GEN-643-003).
• Robot Controller and Teach Pendant (e.g., NXB-GEN-712-002).

Step-by-Step Instructions

Step 1: Unpacking and Inspection

1. Carefully remove all packaging and shipping restraints from the robot and its components.
2. Inspect the robot arm, controller, and cables for any signs of damage that may have occurred during transit. Check connectors, paint, and casting surfaces. Report any damage to your NexBot representative immediately.
3. Verify that all components listed on the packing slip are present.

Step 2: Mechanical Mounting

1. Using certified lifting equipment attached to the designated lift points on the robot base, carefully lift the robot. The lift points are clearly marked with a hook symbol.
2. Slowly lower the robot onto the prepared foundation, aligning the mounting holes in the base with the anchors in the floor.
3. Install the M24 mounting bolts and washers from the NexBot Drives Mounting Bolt Kit (NXB-GEN-643-003). Hand-tighten all bolts initially.
4. Using a precision level, check that the robot base is level. Use leveling shims if necessary.
5. Once the robot is level, tighten the mounting bolts in a star pattern to an initial torque of 400 Nm.
6. Perform a final torque sequence, again in a star pattern, to the final specification of 750 Nm (553 ft-lbs).
7. Mark each bolt head with a paint pen after final torque is applied to indicate it has been tightened.

Step 3: Electrical and Communication Connections

1. Ensure the main power disconnect is in the OFF position and a LOTO device is applied.
2. Route the main robot power and signal cables from the robot base to the robot controller. Avoid sharp bends and protect the cables from physical damage.
3. Connect the main power cable to the designated terminals in the robot controller. Verify the phasing is correct.
4. Connect the robot signal cables (encoder, brake, etc.) to their corresponding ports on the controller. These connectors are keyed to prevent incorrect installation.
5. Connect the main 480VAC power supply to the controller's main disconnect.
6. Connect the EtherCAT communication cable from your plant network or master PLC to the EtherCAT IN port on the robot controller.

Step 4: Pneumatic and User I/O

1. If End-of-Arm Tooling (EOAT) requires pneumatic power, connect a clean, dry air supply to the user air input port at the base of the robot. The recommended pressure range is 0.5-0.7 MPa (72-101 PSI).
2. For EOAT control, connect user I/O signals to the designated terminal block at the robot base or on the J6 axis flange, as specified by your application design.

Verification

1. Final Inspection: Double-check that all mounting bolts are torqued, all cables are securely connected and routed safely, and the work envelope is completely clear of tools, equipment, and personnel.
2. Power-On Sequence:

• Remove your LOTO device from the main power disconnect.
• Turn on the main disconnect to the robot controller.
• Turn on the controller power.
• Check the teach pendant for any initial startup faults. Address any alarms before proceeding.

1. Brake and Axis Check:

• Using the teach pendant, enable servo power.
• Listen for the audible click of the axis brakes disengaging.
• In T1 (Test) mode at a very low speed (10% or less), jog each robot axis (J1, J2, J3, J4, J5, J6) individually for a small distance in both directions.
• Confirm that each axis moves smoothly and corresponds to the direction commanded on the teach pendant.

Once all verification steps are successfully completed, the NexBot Drives HA014-002 is physically installed and ready for software configuration, safety setup, and programming.
