Enter Command

When writing parameters to the drive from the PLC using MEMOBUS/Modbus communication, the parameters are temporarily stored in the parameter
data area of the drive. To enable these parameters in the parameter data area, the Enter command must be used.
There are two types of Enter commands: Enter commands that enable parameter data in RAM only (changes are lost when the drive is shut off), and Enter
commands that write data into the EEPROM (non-volatile memory) of the drive and enable the data in RAM at the same time.
The following table shows the Enter command data. The Enter command is enabled by writing 0 to register number 0900H or 0910H.
Register No.
0900H
0910H
Note: Because the EEPROM can be written to a maximum of 100,000 times, refrain from writing to the EEPROM too often. The ENTER command registers are write-only.
Consequently, if these registers are read, then the register address will be invalid (Error code: 02H). An ENTER command is not required if reference or broadcast data are
sent to the drive.

ENTER Command Settings when Upgrading the Drive

u
To transfer parameter settings from an earlier Yaskawa model drive to V1000, parameter H5-11 needs to be set in accordance with how the Enter command
functions in the older drive.
If upgrading from a G7 or F7 series drive to V1000, set parameter H5-11 to 0.
If upgrading from a V7 series drive to V1000, set parameter H5-11 to 1.

Description
Select the function for the enter command that saves parameter data to
the drive.
0: Save parameter data that was edited to the drive when the enter
command is given.
1: Parameter data that has been edited is saved when the enter command
is given (compatible with the V7).
