Command/Reference Source Priority Using a PLC
Run Command Source
Table 7 Run Command Source Priority
Note: Dash indicates that the setting has no effect on the source of the Run command.
Frequency Reference Source
Table 8 Frequency Reference Source Priority
Note: 1. When the multi-function input terminals are set up for Multi-Step Speed operation, parameters d1-01 through d1-16 take priority as the source of the frequency reference
(assuming that F6-07 = 1).
2. Dash indicates that the setting has no effect on the source of the frequency reference.
3. Refer to the technical manual for the drive the CC-Link Option is connected to for more details on parameter settings.

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
W0
.
2.
Switch the RYC signal on.
• Data for the monitor code is stored in the PLC’s buffer memory.
Note: Monitor codes and units are listed in
.
◆
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
W2
.
• Set the write data to RW
W3
as needed.
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 register number.
Read command code: MEMOBUS register + 1000H
Write command code: MEMOBUS 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 units, and setting ranges, refer to
and
Extended Command Codes on page 27
.
2. Refer to the MEMOBUS/Modbus Data Table in Appendix C of the technical manual for the drive the CC-Link Option is connected to for a list of monitor data using the
MEMOBUS/Modbus message area.
