8.3.2.Key utilization by communication

The VF-AS1 can use the panel keys on the inverters through external communication.

„Key Monitoring Procedure

Set panel key selection (Communication Number: FA10) to “1” to set the external key mode. How- ever, if communication duration is less than 1sec to avoid an inverter operation shutdown in com- munication disruption, communication must always be maintained, such as monitoring key data and LED data to automatically reset inverter operations to inverter key operation (FA10 = 0). Set to the external communication key mode (FA10 = 1) to disable the key function of the inverters so that in- verter operation will not be affected by pressing of the keys on the inverters. By monitoring key in- formation, which is input by the keys on the inverters in this condition, through inverter key data (Communication Number; FC01), the keys on the inverters can be operated through a controller and other devices.

*When the key mode is the external key mode, key operation as an inverter function is disabled and the inverters cannot be stopped by pressing the STOP key to stop inverter operation. Enable emergency stop through an external terminal or other device when an inverter stop is desired.

Panel Key Selection (Communication Number:FA10)

The panel key selection parameter (Communication Number; FA10) discriminates which keys are to be used, panel keys on the inverters or keys sent by external communication, as panel keys used in panel processing of the inverters.
