C.10 Enter Command
C.10 Enter Command
When writing parameters to the drive from the master using MEMOBUS/Modbus communications, 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.
u
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.
u
H5-11 and the Enter Command
An Enter command is not required when writing registers 0000H to 001FH. Changes to those registers take effect
immediately, independent of the setting in parameter H5-11.
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.
H5-11 Settings
H5-11 = 0
H5-11 = 1
How parameter settings are
enabled
When the Enter command is received from the master. As soon as the value is changed.
Upper/lower limit check
Upper/lower limit check is performed, taking the
settings of related parameters into account.
Checks only the upper/lower limits of the parameters
that were changed.
Default value of related
parameters
Not affected. The settings of related parameters remain
unchanged. They must be changed manually if needed.
Default settings of related parameters are changed
automatically.
Error handling when setting
multiple parameters
Data is accepted even if one setting is invalid. The
invalid setting will be discarded. No error message
occurs.
Error occurs if only one setting is invalid. All data that
was sent are discarded.
