Goodrive300-01 inverter for air compressor Communication protocol
-86-
The address of function code occupies 2 bytes with the high bit is in the front and the low bit in behind.
The range of high and low byte is: high byte—00~ffH; low byte—00~ffH. The high byte is the group
number before the radix point of the function code and the low byte is the number after the radix point.
But both the high byte and the low byte should be changed into hex. For example P05.06, the group
number before the radix point of the function code is 05, then the high bit of the parameter is 05, the
number after the radix point 06, then the low bit of the parameter is 06, then the function code
address is 0506H and the parameter address of P10.01 is 0A01H.

This part is the address definition for communication data. It is used to control inverter operation,
obtain inverter state information as well as relevant inverter parameter setting.
