2-3 Basic specifications of network
The following descri
bes the basic specifications of the network interface.
Item Specifications
Topology Ring
Physical layer 100BASE-TX (IEEE 802.3)
Baud rate 100 [Mbps]
Network Status LED
[COM], [LINK]
2 units
Setup of node address (MAC-ID)
Rotary switch (2-digit) on the front panel
Setup range: 0 to 31 (Default 0)
Communication cycle
(physical data transfer cycle)
0.0833, 0.1666, 0.5, 1 [ms]
Command update period 0.1666, 0.5, 1 [ms]
Control mode
PP: Profile position mode
CP: Cyclic position mode
CV: Cyclic velocity mode
CT: Cyclic thrust mode
Connecting cable
STP (shield twisted pair) cable conforming to category 5e or more of
TIA/EIA-568 standards.
Note: Use the straight wiring.
Cable length
a) Inter nodes: Max. 100 [m] [Under review]
b) Total: Max. 200 [m] [Under review]
Note: Use within the range which satisfied both of the above conditions.
Consult with us when you use exceeding the above b) condition.
Slaves to be connected (axes)
Max. 5 when communication cycle time is 0.0833 ms
Max. 10 when communication cycle time is 0.1666 ms
Max. 32 when communication cycle time is 0.5, 1.0 or 1.0 ms
Notes: • Number of axes when all connected axes are in 16-byte mode.
When in the 32-byte mode, the number of axes connected is one half
that of axes connected in the 16-byte mode because the number of
transmit-receive data blocks is twice that required in the 16-byte
mode (fractions omitted).
• These figures depend on the arithmetic processing power of the host
device.
Data size
16-byte mode: Transmit/receive
32-byte mode: Transmit/receive
Communication error detection CRC-CCITT
