Note: 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.

<1> Refrain from saving data to the EEPROM excessively because the EEPROM used in the drive can only be written to 100,000 times.
Monitor Code
• Sets the code number of the items to be displayed by the monitor. (Refer to Monitor Codes on page 31 ).
• Once the monitor code has been set, the monitor value is stored in register RW
R0
by enabling RYC (the
monitor execute request flag).
• While RW
R0
is updated, RXC (during monitor flag) remains on.
RYC (Monitor Execute Request)
RW
W1
Frequency Setting
• Specifies the source of the frequency reference. The value set to this register becomes the main frequency
reference whenever RYD (frequency setting reference 1) is enabled.
• When RYE (frequency setting reference 2 flag) is enabled, then the value for frequency reference 1 is
written and saved to EEPROM
<1>
.
Note: Parameter o1-03 determines the setting units for the frequency reference.
• RYD (Frequency Reference 1)
• RYE (Frequency Reference 2)
RW
W2
Command Code
• Sets the command code to execute functions such as the fault reset, fault history, parameter read, and so on.
(Refer to Command Codes on page 29 , Extended Command Codes on page 30 .)
• When RYF (command code execution request flag) is enabled, the drive executes the specified command.
Once the command has been carried out, RXF switches on.
Note: The value set to RW
W3
(write data) should be adjusted accordingly to match changes to
any parameter settings.
RYF (Command Code Execute
Request)
RW
W3
Write Data
• Sets the value to be used along with RW
W2
(Command Code) as needed.
• RYF (command code execution request flag) needs to be enabled after the command code and write data
have been set.
