SYHNC100-NIB-22A/W-24-P-D-E23-A012 R900978416
Bosch Rexroth IndraControl Series High-Precision Motion Synchronization Module (Model: SYHNC100-NIB-22A/W-24-P-D-E23-A012; Order Code: R900978416)
(Model Naming Interpretation:
- SYHNC100: Core model prefix of Bosch Rexroth’s motion synchronization lineup, emphasizing “SYNChronization” functionality for 100-series high-performance motion control systems—distinguishing it from basic I/O modules (e.g., IndraControl I/O100).
- NIB-22A/W: Hardware configuration code; “NIB” denotes “Networked Industrial Backplane” compatibility, “22A” specifies 22 digital I/O channels (12 inputs, 10 outputs), and “W” indicates wide-temperature operation (-25℃ to +70℃).
- 24-P-D: Power and signal type identifiers; “24” for 24V DC power supply, “P” for “Push-in” terminal connections (tool-free wiring), and “D” for “Differential” signal support (for noise immunity).
- E23-A012: Communication and protocol codes; “E23” denotes support for Ethernet POWERLINK (IEC 61158) and PROFINET IRT protocols, “A012” specifies firmware version A012 (optimized for multi-axis synchronization).
- R900978416: Bosch Rexroth’s global unique order code, ensuring traceability and compatibility with IndraControl ecosystem components (e.g., IndraDrive drives, IndraWorks engineering software).
- Core Positioning: The “synchronization backbone for multi-axis motion systems,” enabling real-time data exchange and coordinated control between drives, sensors, and upper-level controllers (e.g., IndraControl XM21).)
2. Product Description
The SYHNC100-NIB-22A/W-24-P-D-E23-A012 (R900978416) is a dedicated motion synchronization module developed by Bosch Rexroth for IndraControl industrial automation systems, featuring high-precision time synchronization, multi-protocol communication, industrial-grade ruggedness, and tool-free integration as its core characteristics. It is primarily used in scenarios such as automotive body-in-white welding robot synchronization, printing press web tension control, and semiconductor wafer handling system coordination. Its core value lies in solving the challenges of multi-axis motion lag (common in distributed systems), signal noise interference, and complex wiring—through integrated synchronization protocols and differential signal processing, it ensures sub-millisecond-level coordination between up to 16 axes, with key advantages in four areas:
2.1 High-Precision Motion Synchronization
- Ethernet POWERLINK & PROFINET IRT Support: Integrates dual industrial Ethernet ports (100 Mbps) supporting Ethernet POWERLINK (cycle time ≤1 ms) and PROFINET IRT (isochronous real-time, jitter ≤1 µs)—enabling synchronized data exchange between the module and IndraDrive M servo drives. This ensures multi-axis motion coordination accuracy of ±0.1 ms (e.g., synchronizing 8 welding robots to within 0.1 ms for automotive body welding).
- Distributed Clock Synchronization: Implements IEEE 1588 Precision Time Protocol (PTP) v2, achieving global time synchronization across the motion network with an accuracy of ±100 ns. This eliminates time drift between distributed axes (e.g., conveyor segments in a packaging line) and ensures consistent motion timing even with network latency.
