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.

Register

Name

Description

Request Flag

<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 28

• Once the monitor code has been set, the monitor value is stored in register RW

by enabling RYC (the

monitor execute request flag).

• While RW

is updated, RXC (during monitor flag) remains on.

RYC (Monitor Execute Request)

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)

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 26

Extended Command Codes on page 27

• 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

any parameter settings.

RYF (Command Code Execute
Request)

Write Data

• Sets the value to be used along with RW

(Command Code) as needed.

• RYF (command code execution request flag) needs to be enabled after the command code and write data

have been set.
