Set b1-16 (Run Command Source 2) to 3 (“Option unit”).
Selecting the Source of the Frequency Reference 2
Set b1-15 (Frequency Reference Source 2) to 3 (“Option unit”).
Selecting the Run Command and Frequency Reference Source
By setting one of the multi-function input terminals S1 through S7 to supply auxiliary reference (H1-01 to H1-07 = 2), then the frequency reference
set to b1-15 and the run command source set to b1-16 will become enabled.
■Using a PLC as the Command/Reference Source
Using Parameters to Switch Sources
Note: By setting H1- = 2, then parameters b1-15 and b1-16 will become enabled when that terminal is switched on.
• Selecting the Run Command Source
Send write data “3” for command code 2181H to the drive.
The setting for parameter b1-02 changes to “3”.
• Frequency Reference Source Selection
Send write data “3” for command code 2180H to the drive.
The setting for parameter b1-01 changes to “3”.
Using NetRef and NetCtrl
It is also possible to change the source of the frequency reference and the Run command using remote register RWW2 command code 00FBH.
If the power is shut off, however, the drive will use the original setting for the command/reference source once the power is turned back again. This
method should therefore only be used when briefly switching between command/reference sources.

7 Basic Functions

■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 HF-520 Technical Manual 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 RWW0.
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 Monitor Codes on page 29.
◆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 RWW2.
• Set the write data to RWW3 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 Command Codes on page 27 and Extended Command Codes on page 28.
2. Refer to the MEMOBUS/Modbus Data Table in Appendix C of the HF-520 Technical Manual for a list of monitor data using the MEMOBUS/Modbus message area.

◆Remote I/O
The drive takes up a single station address in the buffer memory or the PLC. The table below shows the drive I/O as seen from the PLC side.
Note: Refer to the PLC’s programming manual for information on the PLC’s buffer memory.
■PLC → Drive
Table 9 Remote I/O Table (PLC → Drive)
Note: 1. If making frequent setting changes, use RYD (Frequency Reference 1 flag) for setting the register. Using RYE (Frequency Reference 2 flag) too often can shorten the
performance life of the drive's internal memory.
2. Although RYE and RYF are triggered by the rising edge of the signal, they are otherwise enabled depending on the value that is input.
When switching between monitors using RYC (Monitor Reference), RYC needs to be turned off and then back on again after the monitor code has been changed.
