4.Basic VF-nC1 operations

The VF-nC1 has the following three monitor modes.

Standard monitor mode : The standard inverter mode. This mode is enabled when

inverter power goes on.
After mode is for monitoring the output frequency and setting the frequency
designated value by UP/DOWN key of operation panel. In it is also displayed
information about status alarms during running and trips.	4
• Setting frequency designated values - see 3.1.2
• Status alarm

If there is an error in the inverter, the alarm signal and the frequency will flash alternately in the LED display.

E : When a current flows at or higher than the overcurrent stall level.

R : When a voltage is generated at or higher than the over voltage stall level.

N : When a load reaches 50% or higher of the overload trip value.

J : When temperature inside the inverter rises to the overheating protection alarm level.

All VF-nC1 series of inverters: About 110°C

Setting monitor mode : The mode for setting inverter parameters.

For more on how to set parameters, see 4.1.

Status monitor mode : The mode for monitoring all inverter status.

Allows monitoring of set frequencies, output current/voltage and terminal information.

For more on how to use the monitor, see 8.1.

Pressing the MON key will move the inverter through each of the modes.
