ABB 3BHL000986P9011

Description

Product Description

The ABB 3BHL000986P9011 is a high-precision, dual-channel resolver interface module designed for the ABB AC 800M PLC family. This specialized module serves as a critical link between the control system and high-performance motion feedback devices, converting the analog signals from a resolver into high-resolution digital data for the processor. The 3BHL000986P9011 module is engineered for applications requiring absolute position feedback with extreme reliability and noise immunity, such as in high-speed rotating machinery and precise servo control. Integrating the ABB 3BHL000986P9011 into an AC 800M system provides a robust solution for demanding motion control tasks.

Advantages and Features

1. Exceptional Reliability: Designed for 24/7 operation in harsh industrial environments with high EMI/RFI immunity, thanks to its isolated design and resolver technology’s inherent robustness.

2. High Accuracy and Resolution: Provides precise and stable absolute position feedback without the drift associated with incremental encoders, essential for accurate closed-loop control.

3. Dual-Channel Efficiency: A single 3BHL000986P9011 module can interface with two resolvers, saving space in the I/O rack and reducing overall system cost per channel.

4. Seamless System Integration: Offers tight integration with the AC 800M controller and its Control Software, allowing for straightforward configuration, diagnostics, and data handling within the ABB ecosystem.

5. Long-Distance Capability: Resolver signals can be transmitted over longer distances compared to some low-voltage encoder signals without significant signal degradation.

Application Cases in Various Fields

• Turbo Machinery Control: Provides critical speed and angular position feedback for governor control systems in gas and steam turbines.

• Test Benches & Dynamometers: Used for high-precision torque and speed measurement on engine and transmission test stands where resolver feedback is standard.

• Heavy-Duty Servo Drives: Interfaces with resolvers on large, high-power servo motors in rolling mills, paper machines, and extruders for precise speed and position synchronization.

• Aerospace Ground Support: In equipment for testing aircraft components like actuators and flight control surfaces that utilize resolver feedback.

Comparison with Competing Products

Compared to standard incremental encoder interface modules or analog input cards, the ABB 3BHL000986P9011 excels in specific areas:

• vs. Incremental Encoder Modules: The 3BHL000986P9011 provides absolute position on power-up without a homing routine and is inherently more resistant to electrical noise, whereas incremental encoders can lose position on power loss and are more susceptible to noise.

• vs. Generic Analog Input Cards: This module is a dedicated, intelligent interface. It handles the entire resolver excitation and data conversion chain internally, providing a clean digital value to the CPU. A generic analog card would require external circuitry and significant processor overhead to decode resolver signals.

• vs. Other Brand Resolver Interfaces: Its primary advantage is deep, optimized integration with the ABB AC 800M platform, offering superior diagnostic tools and configuration simplicity within ABB’s engineering environment compared to third-party or generic solutions.

Selection Suggestions and Precautions

1. Platform Compatibility: Ensure your control architecture is based on the ABB AC 800M controller and compatible I/O stations (like S800). This module is not for standalone or other PLC brands.

2. Resolver Compatibility: Verify that your resolver’s electrical specifications (excitation voltage, frequency, transformation ratio) match the configurable ranges of the 3BHL000986P9011 module.

3. Configuration Software: You will need ABB’s Control Software (e.g., Automation Builder) to properly configure and commission the module parameters.

4. Mechanical Considerations: Plan for the module’s physical space in the I/O rack and ensure proper ventilation. Use high-quality, shielded cabling for resolver connections to maximize noise immunity, even though the module itself is robust.

5. Redundancy Requirements: For critical applications, assess if a single module is sufficient or if a hardware-redundant configuration is necessary. The ABB 3BHL000986P9011 supports integration into redundant system architectures.
