- Explanation
This variable can be used to reference inverter status information.
The information to be referenced is defined as follows:
STATUS
bit0 : Run
bit1 : Trip
bit2 : Reserve
bit3 : Retry
bit4 : Overload suppression
bit5 : Overcurrent suppression
bit6 : Overvoltage suppression
bit7 : Reset
bit8 : Under voltage
bit9 to 15 : Reserve
- Sample program :
This program keeps turning on contact output while overvoltage restraint is applied.

1-word data
Readable
- Explanation
This variable can be used to reference the inverter DC voltage.
The data referenced with this variable corresponds to the
data monitored by the DC voltage monitoring function (d102). This variable is read-only.
- Sample program :
This program turns on contact output when the DC voltage exceeds 350 V.
