Defining Features
Integrated Holding Brake
Spring-engaged, electrically released holding brake provides axis security when motor power is removed. Essential for vertical axes to prevent uncontrolled descent under gravity. Rated to hold axis stationary during machine idle periods, emergency stops, or power interruptions.
Serial Encoder Technology
Digital serial encoder provides robust position feedback in electrically noisy industrial environments. Offers superior noise immunity compared to analog systems and includes real-time encoder health monitoring for proactive maintenance.
System Integration
Operates within Fanuc's βi servo drive system: CNC Controller → βi Series Servo Amplifier → A06B-0162-B575#0008 Motor. The amplifier auto-identifies motor parameters on powerup, while axis-specific settings remain stored in the CNC controller.
Typical Applications
- CNC lathe Z-axis and cross-slide drives
- Compact vertical machining center Z-axis spindle head drives
- CNC turret punch ram and Y-axis positioning
- Vertical slide drives on semi-automated assembly equipment
- Small-format five-axis machine rotary and tilt axis drives
- Column and knee drives on bed-type milling machines
- Gantry loader vertical axis positioning
- Tool magazine and automatic tool changer drive axes
Installation & Testing Guidelines
After installation, verify brake operation by confirming full release when energized and complete engagement when de-energized. On vertical axes, test brake holding capability at mid-travel position before running automatic cycles. Document brake wiring configuration before replacement.
Sourcing Considerations
The complete part number including B575 suffix and #0008 brake option must be matched exactly. Consider cable replacement during motor swaps on older machines. Qualified remanufactured units can provide cost-effective alternatives when accompanied by proper documentation.
Frequently Asked Questions
What servo drives are compatible with this motor?
Designed for Fanuc βi series servo amplifier modules in CNC cabinets running Fanuc Series 0i-D, 0i-F, and related βi system configurations.
When is the #0008 holding brake required?
Essential for any axis requiring position holding when de-energized, particularly vertical axes where gravity would cause uncontrolled movement without brake engagement.
Are B5xx suffix variants interchangeable?
No. The B575 suffix specifies encoder type and connector configuration. Other variants may have incompatible connectors or encoder protocols.
Is controller reconfiguration required after replacement?
The amplifier auto-loads standard motor parameters, but axis-specific settings stored in the CNC controller must be restored from a parameter backup.
How should the brake be tested after installation?
Verify full brake release when energized and complete engagement when de-energized. On vertical axes, confirm axis holds stationary at mid-travel before automatic operation.
