SynqNet Features

SynqNet is the only motion control network that offers all of the following:

  • Centralized software and control with distributed hardware.

  • Choice of motor/drive vendors. Choose from a variety of SynqNet motor/drive vendors (Yaskawa, AMC, Panasonic, etc.).

  • Support for up to 64 coordinated axes.

  • Support for up to 64 coordinated nodes on one network.

  • Support for up to 32 bits of configurable I/O per axis.

  • Network bandwidth for torque updates up to 48kHz (4axes)

  • Real-time digital network connection.

  • Plug 'n' Play nodes. SqNode library automatically identifies and configures nodes by type.

  • Automatic network configuration and integrity check.

  • Network Fault Recovery with Ring Topology
    In a ring topology, if any one cable fails, the network will redirect packet data around the break and notify the application with an event. The location of the break can be determined by the application.

  • Failed Node Tolerance
    If one or more nodes fail, the network will continue to operate in SYNQ mode, communicating with the good nodes.

  • Scalable Networking Timing
    The MPI automatically scales the packet timing based on the node number and type. The maximum controller/network sample rate and servo control latency depends on controller/network load. The minumum sample rate is 1kHz.

  • The use of inexpensive cable to communicate between controller and drive (100baseT Ethernet cable), which can transfer more data than traditional serial cables, thereby reducing wiring and maintenance costs.

  • Cable Length
    Network cable lengths of up to 100 meters are supported. The network timing calculations automatically compensate for various cable lengths. The MPI also supports configurable cable lengths.

  • Software Configurable Data Packets
    The MPI automatically configures the packets during network initialization based on the node type. The MPI also supports user configurable packets.

  • SynqNet Topologies
    String (open or closed), Dual String, and Ring topologies are supported.

  • Time-Based Capture
    This is a special technique to derive a captured position from a node's latched time value, the controller's actual position, and the previous sample's actual position. This feature is useful for high accuracy capturing when the controller reads position feedback from a drive (not from the node's FPGA).

  • Centralized software tools for drive configuration, tuning, and diagnostics that are in real-time. Motion Console, Motion Scope, VM3, Bode Tool, and MPX.

  • Remote diagnostics for nodes and drives.

  • Drive setup, configuration, and current loop tuning through the network, from a centralized PC (host). This eliminates the time consuming and error-prone process of connecting a serial cable to each drive in the system in succession.

  • Ability to develop custom nodes.

  • Widely available network components. (i.e. standard connectors and cables are used).

  • Node-to-Node transformer isolation for robust noise immunity.

  • Bad Packet Feedback Compensation
    The controller maintains the previous sample's actual position and calculates the actual velocity. If the feedback packet is corrupted, the controller will interpolate the expected actual position. This feature prevents motor jumps due to network data integrity problems.

  • Topology Save to Flash
    The network topology can be saved to the controller's flash. After a reset, the controller will automatically initialize the network and verify that the number and type of discovered nodes match the expected topology.

  • SynqNet eliminates the ground loops and common-mode electrical noise that are the root cause of many intermittent and systematic motion performance problems.

  • Node FPGA download via SynqNet
    RMB-10v (via Outrigger circuit) and all other supported nodes (via Bowsprit circuit).
