Step3. PC requests the inverter to read the value of P.195, using the format B:
ENQ

195 minus 100 equals 95, then invert 95 to hexadecimal H5F, and
convert
5 and F to ASCII CODE
H35
、
H46.
Step4. After inverter receives the information and processes without error, it sends value of P.195 to
PC, using the format E:

Example 4.
Change value of P.195 to 50 (initial value is 60):
Step1 and step 2 are the same as step1 and step2 of example 3.
Step 3. PC requests the inverter to inputting 50 into P.195, using the format A:
ENQ

195 minus 100 equal 95, then
Minimum unit of P.195 is 0.01, therefore
convert 95 to hexadecimal H5F, 50*100=5000, then convert 5000 to
H5F+H80=HDF. Hexadecimal H1388, and convert 1,3,8,8
to ASCII CODE to send out.
Step 4. After receiving and processing accurate, the inverter responsed PC, using the format C:

Example 5.
Change value of P.195 to 500 (Parameter range 0~400):
Step1 and step 2 are the same as step1 and step2 of example 3.
Step 3.
PC requests the inverter to
inputting 500 into P.195, using the format A:
