5.4 Overview of Operation Modes
FRENIC-AQUA features the following three operation modes:
„
Running mode : After powered ON, the inverter automatically enters this mode.
This mode allows you to specify the reference frequency, PID command
value and etc., and run/stop the motor with the / / keys.
It is also possible to 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 condition arises, the inverter automatically enters Alarm mode. In
this mode, you can view the corresponding alarm code* and its related
information on the LCD monitor.
*
Alarm code: Indicates the cause of the alarm condition. For details, refer to Chapter 9,
Section 9.1 "Protective Functions" and Section 5.6.5 "Reading alarm information" in
this chapter.
Figure 5.13 shows the status transition of the inverter between these three operation modes. If the
inverter is turned ON, it automatically enters Running mode, making it possible to start or stop the
motor.
