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).
