Kollmorgen RMB-10V2-SynqNet is a Remote Motion Block (RMB) designed to integrate conventional analog drives into a SynqNet motion network. It functions as an analog-to-digital conduit between the SynqNet controller and analog drive hardware, enabling legacy or non-SynqNet drives to participate in a synchronized, digital motion control architecture .
Core Function and Network Role
The RMB-10V2-SynqNet supports up to four axes of high-precision analog drives. Each axis provides DAC outputs for command signals, digital encoder inputs for position feedback (RS422 with broken wire detection), and dedicated opto inputs for amplifier fault, home, and limit switches . The module connects to the SynqNet network via its dedicated connectors, which provide a 100 Mbps synchronous real-time link between the motion controller and the RMB node .
This architecture is specifically intended for situations where a native SynqNet drive is either unavailable or unsuitable for the application. By acting as a bridge, the RMB allows machine builders to retain existing analog servo drives while gaining the benefits of SynqNet’s networked control, including reduced wiring and synchronized multi-axis motion . It is also positioned as a practical tool for rapid prototyping with existing machine components .
I/O and Axis Configuration
Beyond the per-axis encoder and DAC connections, the RMB-10V2-SynqNet node itself provides four analog inputs with ±10V range and 16-bit resolution . Each axis includes one dedicated opto input (configurable for 5V or 24V) and one general-purpose opto input, plus an auxiliary digital encoder input that can be assigned to any axis . The module is available in variations that support either 5V or 24V opto I/O, and certain models include additional commutation DACs for sinusoidal commutation of analog drives .
Compatibility and Configuration Notes
The RMB-10V2-SynqNet supports only SynqNet Phase 2 software. This is a critical compatibility constraint for system integrators working with older Phase 1 installations, as the module will not operate in that environment . Configuration and drive parameter management are handled through the SynqNet node library, with drive-specific structures defined in the associated header files provided with the host software package .
Application Context
The module is typically encountered in multi-axis synchronization applications where analog drives remain in service—such as legacy printing presses, textile machinery, and semiconductor handling equipment. For maintenance and spare-part planning, the RMB-10V2-SynqNet represents a critical bridge component: without it, the SynqNet controller cannot communicate with the analog drive stage. Verification of the specific variation (5V or 24V I/O, with or without commutation DACs) against the installed system configuration is recommended before replacement .
