9.4.5 Data address definition
This section describes the address definition of communication data. The addresses are used
for controlling the running, obtaining the status information, and setting function parameters
of the VFD.
9.4.5.1 Function code address format rules
The address of a function code consists of two bytes, with the high-order bit on the left and
low-order bit on the right. The high-order bit ranges from 00 to ffH, and the low-order bit also
ranges from 00 to ffH. The high-order bit is the hexadecimal form of the group number before
the dot mark, and low-order bit is that of the number behind the dot mark. Take P05.06 as an
example: The group number is 05, that is, the high-order bit of the parameter address is the
hexadecimal form of 05; and the number behind the dot mark is 06, that is, the low-order bit is
the hexadecimal form of 06. Therefore, the function code address is 0506H in the hexadecimal
form. For example, the parameter address ofP10.01 is 0A01H.

Note:
The parameters in the P99 group are set by the manufacturer and cannot be read or

modified. Some parameters cannot be modified when the VFD is running; some cannot
be modified regardless of the VFD status. Pay attention to the setting range, unit, and
description of a parameter when modifying it.
