Example 2.
Read the parameter P.195 value by the position machine
Step 1. The position machine sends message to the inverter for reading the value
of P.195.The address of P.195 is H00C3.

Step 2. Once the message is received and processed without mistake, the inverter will send
the content of P.195 to the position machine.

Because the decimal form of H1770 is 6000 and the unit of P.195 is 0.01, P.195 is 60 (6000
x 0.01 = 60).
Example 3.
Change the content of P.195 to 50.
Step 1. The position machine sends message to the inverter for writing 50 into P.195.
