Monitoring the inverter

4.2.1

Monitoring of output current and output voltage

• Press on the operation panel in the monitor mode to switch the monitor item between output frequency, output current,
and output voltage.
Operating procedure
1.
Press during inverter operation to monitor the output frequency. [Hz] indicator turns ON.
2.

whether the inverter is running or at a stop. The unit of current "A" appears.
3.
Press to monitor the output voltage. The unit of voltage "V" appears.
NOTE
• Other monitor item, such as output power or set frequency, is also available. Use Pr.52 Operation panel main monitor

the output current can be monitored.
2.
Press for a while (1 second). The output current monitor screen is set as the first priority monitor screen.
