Monitoring
The following items can be monitored using U constants.
* 1. The status indicator is not turned ON.
* 2. Refer to the next page for input/output terminal status.
* 3. The display range is from −99.9 to 99.99 kW.
When regenerating, the output power will be displayed in units of
0.01 kW when
−9.99 kW or less and in units of 0.1 kW when more
than
−9.99 kW.
