Command – 06 The 06 command reads a single parameter
value from the inverter, which is specified by
the data field this read command.
The receive frame includes an ACK
(acknowledge) character, followed by an
8-byte data field.
Use the codes in the table below to return parameters for H03 and H203 (motor capacity selec-
tion).

STX Control code (STart of TeXt) 1 byte STX (0x02)
Node Node (station) address of inverter 2 bytes 01 to 32
Command Transmission command 2 bytes 06
Data Parameter specified to be read 4 bytes (see tables below)
BCC Block check sum code 2 bytes Exclusive OR of Node,
Command, and Data
[CR] Control code (carriage return) 1 byte [CR] (0x0D)
