Question
What are the specific NexBot Robotics robot models and joint axis positions that are certified for use with the NXB-SRV-AC111-013 AC Servo Motor?
Answer
The NexBot Robotics AC111-013 AC Servo Motor (SKU: NXB-SRV-AC111-013) is a high-performance component engineered for applications requiring rapid acceleration and precise positioning. Due to its specific design characteristics, including low rotor inertia and a compact frame (110 x 110 x 215 mm), it is exclusively approved for use on the wrist axes of select NexBot Robotics articulated robots.
These axes (J4, J5, J6) are responsible for the orientation of the end-of-arm tooling and demand the dynamic response that the AC111-013 motor provides.
Official Compatibility List
The NXB-SRV-AC111-013 is compatible with the following robot series and joint positions:
| Robot Series | Compatible Joint Positions | |-------------------|----------------------------| | NexBot R-20 | J4 (Wrist Twist) | | | J5 (Wrist Bend) | | | J6 (Wrist Flange) | | NexBot R-50 | J4 (Wrist Twist) | | | J5 (Wrist Bend) | | | J6 (Wrist Flange) |
Note: This motor is not designed or approved for use on the major axes (J1, J2, J3) of these robots, as those positions require motors with different torque and braking specifications.
Key Specifications of NXB-SRV-AC111-013
To ensure proper system integration, confirm that the robot controller and drive parameters match these motor specifications:
- Voltage: 480VAC
- Continuous Torque: 4.1 Nm
- Communication Protocol: PROFINET
- Ingress Protection: IP65
Using the NXB-SRV-AC111-013 in any non-approved robot model or axis position can lead to poor performance, premature component failure, and may void the system warranty.
Tips for Technicians
- Verify Part Number: Before beginning a replacement, always physically verify that the part number on the new motor matches NXB-SRV-AC111-013. Counterfeit or incorrect parts can cause significant damage to the robot drive and controller.
- Firmware Compatibility: When replacing a motor, ensure the robot controller's firmware is up to date. Compatibility issues can sometimes arise from outdated software configurations. Check the latest release notes for your controller model for any motor-related updates.
- Parameter Loading: After installation, the correct motor parameters must be loaded from the robot's configuration file. Failure to do so will result in axis following errors, vibration, or complete failure of the motor to enable.
