Request Flag
RW
W0
Monitor Code
•
Sets the code number of the items to be displayed by the monitor.
•
The monitor value is stored in register RW
R0
by enabling RYC (the monitor
execution request flag) after the monitor code has been set.
•
While RW
R0
is updated, RXC (during monitor flag) remains ON.

Command Code
•
Sets the command code to execute functions, for example the fault reset, fault
history, and parameter read.
Note:
Refer to the MEMOBUS/Modbus Data Table in Appendix C of the instruction
manual for D1000 the CC-Link option is connected to for a list of monitor data
using the MEMOBUS/Modbus message area.
•
When RYF (command code execution request flag) is enabled, the drive executes the
specified command. When the command is carried out, RXF switches ON.
Note:
The value set to RW
W3
(write data) should be adjusted accordingly to match
changes to any parameter settings.
RYF (Command Code Execute Request)
RW
W3
Write Data
•
Sets the value to be used along with RW
W2
(Command Code) as needed.
•
Enable RYF (command code execution request flag) after you set the command code
and write data.
Note:
Use the extended command code 280 (Hex.) to set the DC bus voltage reference.
