C.10 Enter Command
C.10 Enter Command
When writing parameters to the drive from the PLC using MEMOBUS/Modbus communication, parameter H5-11
determines if an Enter command must be issued to enable these parameters or not. This sections the types of Enter
commands and how they work.
◆
Enter Command Types
The drive supports two types of Enter commands as shown in
. An Enter command is enabled by writing 0 to
register number 0900H or 0910H. These registers can only be written to. An error will occur if the user attempts to read
from these registers.
Table C.7 Enter Command Types
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.
Register No.
Description
0900H
Writes data into the EEPROM (non-volatile memory) of the drive and enables the data in RAM at the same time. Parameter changes remain even if the power
supply is cycled.
0910H
Writes data in the RAM only. Parameter changes are lost when the drive is shut off.
