4.7.3. Parameter access method

- Example 1: Read access

A controller node reads the value of Input terminal information (address

fd06

). Now, Only R

terminal turns ON (value equals 0002h). The controller node sends/receives the following data.

field

Transmit (nviInvP)

Receive (nvoInvP)

mode_usi

1 1

parano_usl

FD06h FD06h

paradat_usl

0000h 0002h

- Example 2: Write access

In case of controlling FL relay terminal, the controller node writes

fa50

parameter (In this case, set

f132

= 38 before the access). The data value is 0001 hex. The controller node sends/receives the

following data.

field

Transmit (nviInvP)

Receive (nvoInvP)

mode_usi

2 2

parano_usl

FA50h FA50h

paradat_usl

0001h 0001h

- Example 3: Illegal access

Illegal data is written to the inverter parameter

f171

, (Base frequency voltage, address 0171).

The upper limit value is 330.0V (200V class). In case of writing 360.0V, the unit of this parameter is

0.1V and the data value is converted to hexadecimal, so the value is 0E10 hex. The controller node

sends/receives the following data.

field

Transmit (nviInvP)

Receive (nvoInvP)

mode_usi

3 FFh

parano_usl

0171h 0171h
