Article

This document outlines the standard procedure for installing the NexBot Safety MA012-008 6-Axis Robot Arm (SKU: NXB-ROB-MA012-008). Proper installation is critical for ensuring the safety, performance, and longevity of the robotic system. This guide is intended for certified technicians with experience in industrial machinery and robotics.

Prerequisites

Before beginning the installation, ensure all the following conditions are met.

Safety Precautions

• WARNING: Installation must be performed by qualified personnel only. Failure to follow safety procedures can result in serious injury or death, as well as damage to the equipment.
• The main electrical disconnect for the robot controller and related equipment must be in the OFF position and locked out (Lockout/Tagout) before making any electrical connections.
• Ensure the installation area is clear of personnel not directly involved in the process.
• Personal Protective Equipment (PPE), including safety glasses, steel-toed boots, and gloves, must be worn at all times.

Site Preparation

• The mounting surface must be a rigid, flat, and level foundation capable of withstanding the robot's static weight and the dynamic forces generated during operation. Refer to the official site preparation manual for detailed foundation specifications.
• The robot base has a footprint of 650 x 580 mm. Ensure adequate clearance around the robot to accommodate its full 1710 mm reach and any end-of-arm tooling (EOAT).
• Ambient temperature and humidity must be within the operating range specified in the product datasheet.
• Ensure 480VAC, 3-phase power is available at the installation site with appropriate circuit protection.

Required Components

• NexBot Safety MA012-008 Robot Arm (NXB-ROB-MA012-008)
• NexBot Controller (e.g., NXB-CTL-212-006)
• Teach Pendant
• All necessary power and communication cables (e.g., NXB-CBL-NET533-005 for PROFINET)
• Mounting hardware (M16 Grade 10.9 bolts or higher, washers, and nuts)

Step-by-Step Instructions

Part 1: Mechanical Installation

1. Unpacking and Inspection: Carefully unpack the robot from its shipping crate. Visually inspect the robot arm, cables, and connectors for any signs of damage that may have occurred during transit. Report any damage immediately.
2. Lifting and Positioning: Use certified lifting equipment (e.g., overhead crane, forklift with boom attachment) with a capacity exceeding the robot's shipping weight. Attach lifting straps only to the designated lifting points indicated on the robot body. Slowly lift the robot and position it over the prepared mounting foundation.
3. Mounting the Robot: Gently lower the robot onto the mounting surface, aligning the holes in the robot base with the mounting holes in the foundation. Install the M16 mounting bolts with flat washers. Do not fully tighten the bolts at this stage.
4. Leveling: Using a machinist's level or laser level, check the level of the robot's mounting base. If necessary, use industrial-grade shims to achieve a level state within ±0.5 mm across the base. An unlevel base can negatively impact the robot's repeatability (±0.04 mm) and cause premature wear on joints.
5. Final Torquing: Once the base is perfectly level, tighten the mounting bolts in a star pattern to ensure even pressure. Torque all M16 bolts to 180 Nm (133 ft-lbs). Re-verify the level after torquing is complete.

Part 2: Electrical Installation

1. Confirm Power is Off: Double-check that all power sources are de-energized and that Lockout/Tagout procedures are still in effect.
2. Grounding: Connect the main grounding conductor from the robot controller cabinet to the facility's earth ground. Connect the grounding cable from the robot arm to the designated grounding point on the controller. Proper grounding is essential for safety and noise immunity.
3. Connect Robot to Controller: Connect the main robot power and signal cables from the base of the MA012-008 to the corresponding ports on the robot controller (e.g., NXB-CTL-212-006).
4. Connect Main Power: Connect the 480VAC 3-phase facility power to the main input terminals of the robot controller. Ensure all connections are secure and comply with local electrical codes.
5. Connect Communications: Connect the PROFINET communication cable (e.g., NXB-CBL-NET533-005) from the PLC or main network switch to the PROFINET port on the robot controller.
6. Connect Safety Circuits: Wire all external safety circuits, such as emergency stop buttons, safety gates, and light curtains, to the safety I/O terminals in the controller. Refer to the controller's hardware manual for detailed safety circuit diagrams.

Verification

1. Pre-Power-Up Inspection: Remove all tools and equipment from the robot's work envelope. Perform a final visual inspection of all mechanical and electrical connections. Ensure all controller cabinet doors are closed and secured.
2. Initial Power-Up: Clear all personnel from the safety-fenced area. Remove the Lockout/Tagout devices and energize the main disconnect. Power on the robot controller and observe the system status on the teach pendant.
3. Check for Errors: Verify that no critical errors or alarms are present on the teach pendant. Resolve any communication or configuration errors before proceeding.
4. Axis Movement Test: Using the teach pendant and at a very low speed (10% or less), carefully jog each of the robot's six axes (J1 through J6) in both directions for a short distance. Listen for any unusual noises and ensure movement is smooth. Verify that the robot's movement corresponds to the commands from the teach pendant.
5. Calibration Check: It is highly recommended to perform a mastering or calibration verification procedure after installation to ensure the robot's positional accuracy is within specification. Refer to the software manual for the correct procedure.
