Reading and Setting Parameters

The PLC can write drive parameters, read drive data and operation status, and change
settings.
Follow the directions below.
1.
Set the command code to remote register RW
Set the write data to RW
2.
Switch ON the RYF signal (request to execute the command code).
• Drive executes the process and reply data that correspond with the command
code.
• Command codes for drive parameters should be calculated by adding the
values shown below to the MEMOBUS/Modbus register number.
Read command code: MEMOBUS/Modbus register + 1000 (Hex.)
Write command code: MEMOBUS/Modbus register + 2000 (Hex.)
Example: Acceleration time command code for C1-01 [Acceleration Time 1] is
200 (Hex.). Get the read command code by adding 1000 (Hex.), yielding 1200
(Hex.).
Note:
1. For a list of command codes, write data drives, and setting ranges, refer to the instruction manual
for the drive the CC-Link Option is connected to.
