Communication parameter group 07
PARAMETER DESCRIPTION 118
Step 1: Use upper controller to send FA command in Format A：
ENQ
Inverter station
number 0 Code
HFA
Waiting time
Data
H0000 Check code
Sum Check
CR
H05 H30 H30 H46 H41 H30 H30 H30 H30 H30 H44 H37 H0D
Step 2: After receive and processing the data without error, inverter will send reply to upper controller in Format C：
ACK
Inverter station
number 0
CR
H06 H30 H30 H0D
Example 3. Upper controller reads the value of 01-28(P.162)：
Step1: Upper controller sends write and page change command, using Format A：
ENQ
Inverter station
number 0 Code
HFF
Waiting time
Data
H0001 Check code
Sum Check
CR
H05 H30 H30 H46 H46 H30 H30 H30 H30 H31 H44 H44 H0D
P.162 is on page 1
Step 2: After receive and processing the data without error, inverter will send reply to upper controller in Format C：
ACK
Inverter station
number 0
CR
H06 H30 H30 H0D
Step 3: Upper controller requests inverter for reading 01-28(P.162) value using Format B：
ENQ
Inverter station number
0 Code
H3E
Waiting time
Check code
Sum Check
CR
H05 H30 H30 H33 H45 H30 H30 H38 H0D
Subtract 100 from 162 (=62)，convert 62 to H3E in hex，then convert E to H33、H45 in ASCII
Step 4: Once inverter receives and processes the data without error, 01-28(P.162) value will be sent to upper
controller in Format E:
STX
Inverter station
number 0 Read out data
HFFFF
Unit ETX
Check data
Sum Check
CR
H02 H30 H30 H46 H46 H46 H46 H32 H03 H41 H41 H0D
Example 4. Change the content of 01-28(P.162) to 50 (Default setting is 99999).
Step 1~2 are the same as Step 1~2 of Example 3;
Step 3: Upper controller requests inverter to write 50 in 01-28(P.162) in Format A：
ENQ
Inverter station
number 0 Reference
code HBE
Waiting time
Data
H1388 Check code
Sum Check
CR
H05 H30 H30 H42 H45 H30 H31 H33 H38 H38 H45 H42 H0D
Subtract 100 from 162(=62)， minimum unit of 01-28 is 0.01, hence 50×100=5000,
Convert 62 to H3E in hex， then convert 5000 to H1388 in hex,
H3E+H80=HBE then convert 1、3、8、8 to ASCII for transmission
Step 4: After receive and processing the data without error, inverter will send reply to upper controller in Format C：
