• 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 re 1000 (Hex.)
Write command code: MEMOBUS/Modbus re 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.
