6.15.9 Data transmission examples
Examples of data transmission using standard format 2 are described below.
Conditions
Function code U11 "SX transmission format selection" = 3, H30 "Link Operation" = 3, maximum speed:
1500 r/min,
E-SX bus station address: 10, E-SX master station address: 254, E-SX bus used
(1) Speed setting / run command
Issuing run forward (FWD) and 750 r/min speed commands from the MICREX-SX
%QW254.0.10.12 2 7 1 0 750 ÷ 1500 × 20000 = 10000 = 2710(hex)
%QW254.0.10.13 0 0 0 1
FWD = 1
(2) Method of using function code monitor
Constant monitoring from the MICREX-SX of the calculated torque value M07 and the effective
output current value M11.
Set o160 = 0807 (hex) and o161 = 080B (hex) in advance.
(485No. of M07 is 0807 (hex), 485No. of M11 is 080B (hex))
