3.2 Overview of Operation Modes
The keypad 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 the protective
function detailed in the FRENIC-HVAC/AQUA User's Manual, Chapter 9 or FRENIC-Ace
User's Manual, Chapter 6, and in the detailed PDF version of the multi-function keypad
instruction manual, Section 3.4.5 "Reading alarm information."
Figure 3.3 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.
