Installation Guide: NexBot Robotics MD132-016 Multi-Axis Servo Drive

SKU: NXB-SRV-MD132-016 | Revision: 1.0 | Category: Drive Systems > Servo Drives > Multi-Axis Servo Drives

DANGER: Disconnect all power sources before beginning installation. Follow lockout/tagout (LOTO) procedures per OSHA 1910.147.

1. Required Tools & Materials

2. Pre-Installation Checks

  1. Verify the product SKU on the packaging is NXB-SRV-MD132-016.
  2. Inspect the anodized aluminum housing for any signs of shipping damage.
  3. Confirm the control cabinet provides at least 50mm of clearance above and below the drive's 245mm height for proper ventilation.
  4. Ensure the incoming 480VAC 3-phase power supply is de-energized and locked out before beginning installation.
  5. Verify the mounting backplane is a clean, conductive, and grounded surface capable of supporting the drive's 4.2 kg weight.
  6. Check that all motor power, encoder feedback, and shielded EtherCAT cables are present and of the correct length.

3. Installation Procedure

Step 1: Mounting the Drive

Secure the MD132-016 drive vertically to the cabinet's grounded backplane using all provided mounting points. This orientation is critical for proper passive and active cooling. The drive's compact 75mm width allows for high-density installations.

Warning: The drive weighs 4.2 kg. Use proper lifting techniques and ensure the mounting panel is adequately supported.

Step 2: Protective Earth (PE) Connection

Connect the main PE terminal on the drive to the central star grounding point of the control cabinet. Use a low-impedance, appropriately sized green/yellow wire to ensure safety and minimize electrical noise.

Step 3: Connecting 480VAC Input Power

Connect the three-phase 480VAC supply lines to the L1, L2, and L3 input terminals. Use the specified wire gauge and tighten the terminals to the recommended torque value to prevent overheating.

Warning: Ensure the main power source is locked out and tagged out (LOTO) before making any power connections. Hazardous voltage is present.

Step 4: Connecting Motor Power Cables

Connect the motor power cables for Axis 1 and Axis 2 to their respective U, V, W output terminals. Ensure the correct phase sequence is followed to achieve the intended direction of rotation.

Step 5: Connecting Encoder Feedback

Plug the motor encoder cables for each axis into the corresponding high-density feedback connectors (XFB1, XFB2). Ensure the connectors are fully seated and secured with their locking mechanisms to prevent signal loss from vibration.

Step 6: Connecting EtherCAT Network

Connect the incoming EtherCAT cable from the master or previous slave device to the 'XEC1 IN' port. Connect the outgoing cable to the 'XEC2 OUT' port to continue the network chain. Use shielded CAT5e or higher-grade cables.

Step 7: Wiring the Safe Torque Off (STO) Circuit

Connect the machine's safety relay outputs to the drive's STO input terminals. This connection is fundamental for implementing a safe system and must be wired according to your machine's risk assessment.

Warning: Improper STO wiring can defeat the safety function and lead to unexpected machine motion, causing severe injury.

4. Post-Installation Verification

  1. Verify all terminal covers and protective shields are securely re-installed on the MD132-016.
  2. Remove all tools, wire scraps, and other foreign objects from the control cabinet.
  3. With main power off, apply 24VDC control power and verify the drive's status LED shows a ready state without faults.
  4. Test the machine's E-Stop circuit to confirm the STO function is triggered correctly on the drive.
  5. Close and secure the control cabinet door before applying main 480VAC power.
  6. After applying main power, check the drive's diagnostic display or software for any initialization faults before enabling the axes.
