Vout; Power - Hitachi NT2021XA Instruction Manual

Variable name

Vout

Output voltage monitoring
- Explanation
This variable can be used to monitor the inverter output voltage. The data monitored with this variable corresponds to the data
monitored by the output voltage monitoring function (d013). This variable is read-only.
- Sample program : Program to turn a contact output on when output voltage exceeds 200 V

Variable name

Power

Power monitoring
- Explanation
This variable can be used to monitor power input to the inverter. The data monitored with this variable corresponds to the data
monitored by the power monitoring function (d014). This variable is read-only.
- Sample program : Program to output a signal when input power is lower than the specified minimum limit or higher than the
specified maximum limit
