Run-Time; On-Time - Hitachi NT2021XA Instruction Manual

Chapter 2 Syntax
Variable name

RUN-Time

Cumulative operation
RUN time monitoring
- Explanation
This variable can be used to monitor the accumulated running time of the inverter. The data monitored with this variable
corresponds to the data monitored by the cumulative operation RUN time monitoring function (d016). This variable is read-only.
- Sample program : Program to output a one-second pulse signal indicating the running time of the inverter to a contact output
every hour
Label Mnemonic

Variable name

ON-Time

Cumulative power-on time
monitoring
- Explanation
This variable can be used to monitor the accumulated power-on time of the inverter. The data monitored with this variable
corresponds to the data monitored by the cumulative power-on time monitoring function (d017). This variable is read-only.
- Sample program : Program to convert the power-on time into a number of days and output the converted data as word data to
Y (00) to Y (05)
