Sub-command
code
Data (request) Data (response) Function
slave with fault.
0x0030
0x0000 0x0000
Setting the slave not to respond to invalid or wrong
commands.
0x0001 0x0001
Setting the slave to respond to invalid and wrong
commands.
4. Change multiple function code parameters and control parameters of the drive, and the parameter
values will not be saved after power off. When this command is used, the parameter value changed will not be
saved upon power on after power off.
The application-layer protocol data units are as follows.
Request format:
Application-layer protocol data unit Data length (number of bytes) Value or range
Command code 1 0x10
Start register address 2 0x0000~0xFFFF
Number of registers in operation 2 0x0001~0x000A
Number of bytes of register content 1 2 * Number of registers in operation
Register content 2 * Number of registers in operation
If the operation is successful, the response frame is as follows:
Application-layer protocol data unit Data length (number of bytes) Value or range
Command code 1 0x10
Start register address 2 0x0000~0xFFFF
Number of registers in operation 2 0x0001~0x000A
This command is used to change the content of the continuous data cells from the start register address. If the
operation is failed, it will return to the abnormal response frame and its format is as shown above.
5. Change single 16-byte function code parameters and status parameters of the drive, and the parameter
values will be saved after power off. The command code 0x41 is used to change the single 16-byte function
code parameters or control parameters of the drive, and store the value into the nonvolatile memory cell. Its
command format is the same as that of 0x06. The only difference is as follows: the parameter value changed
under the 0x06 command will not be saved upon power off, but the parameter value changed under the 0x41
command will be saved upon power off.
6. Manage the drive function codes
The management of the drive function codes includes reading the upper/lower limit of the parameter, reading
the parameter features, reading the maximum group internal index of the function code menu, reading the
next/previous function group number, reading current display status parameter index, displaying the next
status parameter and reading the factory-leave value of the function code parameter.The parameter features
include the read/write features, units and scaling relations of the parameter.
