Enter Command

When you use MEMOBUS/Modbus communications to write parameters from the PLC to the drive, the H5-11
[Comm ENTER Command Mode] setting sets the function to enable these parameters from the Enter command.
This section gives information about the Enter command.
Types of Enter Commands
The drive supports the two Enter commands shown in Table 5.8.
Write 0 to register number 0900 or 0910 (Hex.) to enable the Enter command. You can only write to these
registers. If you read to these registers, it will cause an error.
Register No.
(Hex.)
When you write parameter data to the EEPROM, you will enable the data on the RAM at the same time.
0900
This process saves the parameter changes until you de-energize the drive.
This updates the data on the RAM, but does not write data to the EEPROM.
0910
This process saves the parameter changes until you de-energize the drive.
Note:
• You can write the EEPROM to the drive a maximum of 100,000 times. Do not frequently execute the Enter command (0900 (Hex.))
that is written to EEPROM. The Enter command register is write-only. If this register is read, it will cause a Register Number Error (02
(Hex.)).
• When the command data or broadcast message is transmitted to the drive, the Enter command is not necessary.
Functions of the Enter Command when Replacing a Previous Generation Drive
When you replace a previous generation Yaskawa drive with this product, you must set the Enter command
function for this product the same as the previous product. The Enter command function is different for Yaskawa
G7, F7-series, and V7-series drives.
Use H5-11 to set the Enter command function:
• When replacing G7 and F7 series drives, set H5-11 = 0 [ENTER Command Required].
