Basic Functions

This interface allows the drive to be connected to a CC-Link network as a remote device,
making it possible to operate, adjust settings, and monitor the operation status of the drive
using the PLC program. Both bit and word data cyclic transmission are available, and high
speed communication up to 10 Mbps is possible.
Below is a description of the basic CC-Link functions that can be performed by the PLC.
Note: Set parameters when operating the drive from a PLC. For instructions, refer to
Parameters on page
u
Monitors
The user can monitor drive operating status from a PLC.
To do so, the monitor should be set up as follows:
1.
Sets the monitor code to the remote register RW
2.
Switch the RYC signal on.
Data for the monitor code is stored in the PLC's buffer memory.
Note: Refer to the instruction manual for the drive the CC-Link Option is connected to for a list of
monitor codes and drives.
u
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 + 1000H
Write command code: MEMOBUS/Modbus register + 2000H
EXAMPLE: Acceleration time command code for C1-01 is 200H. Get the read
command code by adding 1000H, yielding 1200H
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.
2. Refer to the MEMOBUS/Modbus Data Table in Appendix C of the instruction manual for the drive the
CC-Link option is connected to for a list of monitor data using the MEMOBUS/Modbus message area.
