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.

Comm. error between drive and CC-Link device
ON: Currently monitoring motor revolutions.
ON: Monitor data has been updated.
ON: Displays the main frequency reference that has been set.
ON: Displays the data set to d1-01 (Frequency Reference 1).
Note: Also sets the main frequency reference at the same time.
ON: Displayed after the specified command code has been executed.
RXF signal switches off when the RYF command is no longer present.
ON: Fault occurred on the drive side.
ON: Drive is ready to operate.

• Sets the code number of the items to be displayed by the monitor. (Refer to
• Once the monitor code has been set, the monitor value is stored in register RW
monitor execute request flag).
• While RW is updated, RXC (during monitor flag) remains on.
R0
• 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.
• 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
• 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 (write data) should be adjusted accordingly to match changes to
W3
any parameter settings.
• Sets the value to be used along with RW
• RYF (command code execution request flag) needs to be enabled after the command code and write data
have been set.
