Command Code
• Sets the command code to execute functions such as the fault reset, fault history,
parameter read, and so on. (Refer to
Drive Command Codes on page 44
Extended Command Codes on page 45
.)
• 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.

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.
<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 Data
• Monitor data is stored according to RW
W0
(Monitor Code).
• Monitor data is updated while RYC (monitor execute request flag) is enabled. RXC
(during monitor) remains on as data is updated.

Output Frequency
• Motor revolutions or output frequency has been set without errors.
Sets data contents with RYB (Motor Revolutions/ Output Frequency Switch).
• When RYB is disabled, the output frequency are stored. Set in the drives specified
by o1-03 (Frequency Reference Setting Drives) in output frequency.
Example: When o1-03 = 0, the frequency is displayed in 0.01 Hz.
When o1-03 = 2, the frequency is displayed as r/min.
• When RYB is enabled, the motor revolutions are stored as r/min. Here, RXB (actual
motor rotations) is enabled.
The output frequency are stored in V/f Control or PM Open Loop Vector mode.
RYB setting is disabled.

Response Code
• Sets 00H when there are no problems with RW
W2
(Command Code) and RW
W3
(Write Data).
• Sets 01H through 03H if an error occurs.
• Response Code:
00h: Normal
01h: Write-mode error (attempted to write during run, etc.)
02h: Command code error
03h: Data setting range error
