8.3.2.Key utilization by communication
The VF-S15 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.
However, if communication duration is less than 1sec to avoid an inverter operation shutdown in
communication 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 inverter operation will not be affected by pressing of the keys on the inverters. By monitoring
key information, 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 control-
ler 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.
