5. Example usage
5.1. Procedure
Lower example shows the procedure to send the 100% speed drive command to the inverter.
1. Commission
Make a network tool to identify this option by using service pin function (refer to network tool
manual in detail).
2. Binding
Refer to next section.
3. Configurations
Set correct value into the configuration properties.
4. Drive command and setpoint
Set the {200, 1} (100% speed drive) into the nviDrvSpeedStpt and propagate it.
5.2. Binding
Network variable bound to the other network variable can transmit/receive the data. “Binding” can be
made by network tool. Network variable has a direction (Input/Output) and individual type (SNVT_type).
Binding to the same direction variable or the different type is prohibited.
