6.15.8 Format details
6.15.8.1 I area (MICREX-SX ← FRENIC-VG)
(1) Standard format 2 (U11 = 3)
1 Polling function code address, polling function code data
(MSB) (LSB)
15 14 1312 11 1098765432 1 0
Polling function code 485No (1)
Polling function code 485No (2)
Data of polling function code (1)
Data of polling function code (2)
The 485No corresponding to the function code in the polling request from the MICREX-SX is
stored in "Polling function code 485No (1), (2)" (16 bits). The data are respectively stored in "Data
of polling function code (1), (2)".
2 Function code monitor
(MSB) (LSB)
15 14 1312 11 1098765432 1 0
Data of function code monitor (1)
Data of function code monitor (2)
"Function code monitor (1), (2)" are constant monitors of function code data. Set the 485Nos. of
the function codes to be monitored in function code o160 for "Function code monitor (1)" and o161
for "Function code monitor (2)".
3 Motor speed
(MSB) (LSB)
15 14 1312 11 1098765432 1 0
Motor speed (decimal) x 20000 ÷ maximum speed ⇒ 16 bit data
The maximum speed is the speed set in inverter function code F03. To use r/min units, calculate
the above equation in reverse. When the data is negative (2's complement), the command becomes
a reverse speed command.
