Variable name

STATUS

Inverter status monitoring
- Explanation
This variable can be used to reference inverter status information.
The information to be referenced is defined as follows:
STATUS
- Sample program : This program keeps turning on contact output while overvoltage restraint is applied.

Variable name

DCV

DC voltage monitoring
- 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.
