Each parameter is represented by 16 bits of data. The communication
address of each parameter is determined by the parameter segment
number and the parameter sequence number. The communication address
has 16 bits of data, of which the high 8 bits are the parameter segment
number and the low 8 bits are the parameter sequence number.

The internal state parameters of the servo drive can be read through the
RS-485 communication port, but they
can’t be written. The state quantity is
stored in 16BIT data, and the value accurate to the decimal place is
amplified by 10 times and 100 times when read out through the
communication port. State parameters are stored in 16-bit data, where the
value is accurate to the decimal place. When they are read out through the
communication port, the value is
multiplied
by 10 times and 100 times.
