6.5.9 Link function
Refer to "6.3.9 Link function" of the T-Link interface.
When both of the SX bus interface card and T-Link interface card are installed, the link function
targets communication via the T-Link.
When only the SX bus interface card is installed and the monitoring format is selected, the link
function targets communication from the integrated RS-485.
6.5.10 Data transmission example
The following explains a data transmission example using the transmission format.
(1) Speed setting
From MICREX-SX, give commands to run forward (FWD) at 750r/min.
(Condition: Function code U11 "SX transmission format selection"= 0, H30 "Link operation"=3,
maximum speed 1500 r/min, SX bus station address: 10)
Give S06 the forward running command (FWD: ON) and S01 the speed command.
%QW10.8 0 6 0 1 Function code S06, S01 selecting (link No. 06h, 01h)
%QW10.9 0 0 0 0 Selecting dummy data
%QW10.10 0 0 0 1 Function code S06 FWD=ON
%QW10.11 2 7 1 0 Function code S01 Speed setting 750/1500*20000=10000=2710(h)
↓ After acceleration completes
%IW10.6 2 7 1 0 Monitor the motor speed.
(2) Torque command monitor
Monitor the torque command value from MICREX-SX.
(Condition: Function code U11 "SX transmission format selection"= 0, SX bus station address: 10)
%QW10.14 1 0 0 0 Torque command monitor (link No. 10h)
%QW10.15 0 0 0 0
↓ After read completes
%IW10.0 1 0 0 0
When the link number requesting polling is returned to this area, reading is completed.
%IW10.1 0 0 0 0 Torque command value monitor data
%IW10.2 1 3 8 8 1388(h)×100(%)/ 10000 = 50(%)
%IW10.3 0 0 0 0 ↓
%IW10.4 0 0 0 0 From the above, the torque command value is "50% of drive".
%IW10.5 0 0 0 0
