NOTE!
In order to have those commands executed, it is necessary that the inverter be programmed to be
controlled via serial. This programming is achieved by means of parameters P0105 and P0220 to
P0228.

MBOX

It is a structure that allows reading and writing CFW701 parameters. The following objects compose this
structure:
ANV100: informs the parameter number

ANV101: informs the datum read from or written into the parameter

BV100: parameter reading command

BV101: parameter writing command

Procedure for reading a parameter via MBOX:
1. Inform the parameter number in the ANV100 object Present Value property;
2. Write 1 in the BV100 object Present Value property;
3. Check the value read in the ANV101 object Present Value property. The read value will be an integer,
without the decimal point representation. E.g., 20.0 will be read as 200 in the MBOX.
Procedure for writing a parameter via MBOX:
