Set Modbus receive type
Set Modbus address
Set Modbus mode to RTU instead of ASCII (new parameter P210)
Sending device must transmit 1-byte binary address, 1-byte binary
function code, n binary message bytes, low byte of crc-16 (initial value
0xffff) of all preceding bytes, high byte of crc-16 of all preceding bytes.
Master device cannot intersperse delays of more than 1.5 character times
into a message to a slave device.

P6001: "Modbus" is used to specify which of the 60 Series parameters are
mapped to which Modbus address. Since Modbus handles the transferring
of data by referencing the data's address, it is necessary to specify which
parameters are assigned to which Modbus address.
The parameter assigned to the first Modbus address (address 40001) is
specified at P6001 of the setup mode. The subsequent parameters
specified at P6002, P6003, etc.... are then assigned the next available
Modbus address, which is dependent upon the number of registers
required for the preceding parameters.
To specify a parameter, three items are required:
Parameter Number
Instance
Translation Type

The parameter selection process is very similar to other setup modes
requiring a parameter selection.
Press [ENTER] to access the standard parameter selection menu. Then
use the up and down arrow keys to scroll through the menu to find the
desired parameter, then press [ENTER]. Again, use the up and down
arrow keys to scroll through the menu to find the desired instance of the
specified parameter, and press [ENTER] again. Then key in a format code
(from the appropriate table below) and press [ENTER], or press the up
and down arrow keys to cycle through your choices. Then press [ENTER]
to save your choice.
Alternatively, simply key in the parameter number, a decimal point and
then the instance number followed by [ENTER] to specify the parameter.
Then choose the format code as described above.
New parameter entries are inserted in front of the displayed entry. In
effect, you cannot write over a parameter, but you can insert a new one
and delete an old one. If you make an entry in the middle of a list the entry
you were viewing and all the subsequent entries are pushed down to make
room for the new entry.
The relevant formatting codes are dependent upon the parameter's data
type.
