8.3.Utilizing panel (LEDs and keys) by communication

The VF-AS1 can display data that is not related to the inverters through an external controller or other means. Input by key operations can also be executed. The use of inverter resources re- duces the cost for the entire system.

8.3.1. LED setting by communication

Desired LED information can be displayed by communication.

<How to Set>

Set the standard monitor display selection parameter to “communication LED setting (=).”

When in the standard monitor mode status, LED information is displayed according to the setting of Communication Number FA65. (Set to Communication Number FA65 = 1 and initial data “” in shipment setting)

In case of an alarm while setting communication LEDs, the alarm display will alternately display specified LED data and alarm message.

For example, if an over-current alarm (alarm display “”) occurs while “.” is displayed by this function, “” and “.” will be displayed alternately.
