SUNFAR Self-Defined Communication Protocol 81
1.3.6 Command classification 4- Send control command
Main machine sending frame size is 15 bytes, while slave machine response frame
size is 18 types. In normal operation of inverter, the type of frame data is applicable
to maximum extent.

The setting data in the frame sent by main machine is the set frequency sent from
main machine to slave machine.
The running data in the slave machine response frame is running parameter sent by
main machine, which is determined by setting content of monitoring item (function
code: [F3.08]) in inverter functional parameter list, and slave machine responds the
item monitoring value.
The inverter functional parameter list refers to Chapter 5 of
E550 series inverter operation manual: Functional parameter list.
