Key Features and Advantages:
The VT-HNC100-4-3X/P-I-00/G04 revolutionizes motion control with its patented “Adaptive Tuning Technology” that automatically compensates for mechanical resonance and load variations without manual parameter adjustment. Dual-processor architecture separates communication and control tasks, ensuring jitter-free performance even during network load peaks.
Precision control: Achieves positioning accuracy ≤±1 encoder count with 24-bit resolution and 50μs current loop update rate. The amplifier’s “One Cable Technology” option reduces wiring complexity by transmitting power and feedback signals through a single hybrid cable. Maintenance teams benefit from integrated condition monitoring that tracks component wear (capacitors, fans) and predicts service intervals via web interface.
Application Fields:
In CNC machining centers, the VT-HNC100-4-3X/P-I-00/G04 drives high-speed spindles (up to 30,000 RPM) with precision tool path following accuracy ≤5μm. Automotive production lines utilize its synchronous control capabilities for robotic welding arms requiring ≤0.01° angular repeatability.
Packaging machinery applications leverage the amplifier’s electronic cam profile functionality for complex motion sequences, while semiconductor equipment benefits from its ultra-low ripple current (<0.5% of rated current) for sensitive positioning tasks. The Bosch Rexroth VT-HNC100-4-3X/P-I-00/G04 is particularly effective in printing presses where its 100μs synchronization accuracy ensures register mark alignment.

Installation and Maintenance:
Installation preparation: The VT-HNC100-4-3X/P-I-00/G04 requires minimum 100mm clearance on all sides for ventilation and should be mounted vertically on non-flammable surfaces. Verify mains voltage stability (±10% tolerance) and implement proper RFI filtering for CE compliance.
Maintenance recommendations: Perform quarterly cleaning of cooling fins using compressed air (<2bar pressure). Monitor DC link capacitor health via web interface and replace when ESR exceeds 150% of initial value. Firmware updates should be scheduled during planned downtime using Rexroth’s IndraWorks engineering tool.
