Simultaneous keying
Simultaneous keying means pressing two keys at the same time (expressed by "+"). FVR-Micro
supports simultaneous keying as listed below.
(For example, the expression "
+
keys" stands for pressing the
key while holding down the
key.)

About changing of function code data
The function code data can be changed only when the data value displayed on the LED monitor is
flashing.
When the data value is lit, no change is allowed. To change the data, stop the inverter or disable the
data protection.
3.2 Overview of Operation Modes
FVR-Micro features the following three operation modes:
Running mode
: This mode allows you to enter run/stop commands in regular operation.
You can also monitor the running status in real time.
Programming mode : This mode allows you to configure function code data and check a variety of
information relating to the inverter status and maintenance.
Alarm mode : If an alarm occurs, the inverter automatically enters the Alarm mode. In this
mode, you can view the corresponding alarm code* and its related information on the LED monitor.
* Alarm code: Indicates the cause of the alarm condition that has triggered the protective function. For
details, refer to Chapter 8, Section 8.3 "Protective Functions."
Figure 3.1 shows the status transition of the inverter between these three operation modes.
