First 195 minus 100 equals to 95, then convert 95 to H5F hexadecimal digits. Next convert 5 and into H35
and H46, respectively, in ASCII code.
Step 4. Once the inverter receives and processes the data without error, the value of P.195
will be sent to the position machine in Format E:

Example 4.
Change the content of P.195 to 50 (the original factory setting is 60).
Step 1 to 2: Omitted (Same as Step 1 to 2 of Example 3);
Step 3: The position machine requests the inverter to write 50 in P.195 in Format A:

First, 195 minus 100 equals to 95; because the smallest unit of P.195 is 0.01,
Concert 95 to H5F hexadecimal digits, 50 x 100 = 5000; then convert 5000 to hexadecimal
H5F+H80=HDF digits H13888; Then covert 1, 3, 8 and 8 to ASCII
codes for transmission.
Step 4. After receiving and processing the data without error, the inverter will send a reply to
the position machine in Format C:
