Indicators and Motor status
The indicator lights below the display have the following meaning:

The Motor status, shown in the lower left corner of the display, has the following meaning:
Run Motor
is
running.
Stopping
Motor is decelerating towards a stop.
Standby
Inverter standby, waiting for Run signal (DIN1).
Disable
Inverter is not ready or will not accept Run signal.
Waiting
Inverter is waiting for an internal timer to finish.
5.4 Operating
modes
The inverter has four operating modes,
Inhibit
,
Manual, Auto
and
Bus
. When starting and initiating the inverter it
enters the
Auto
mode and the RUN screen is shown. The
Auto
mode is used for controlling the inverter with an
external start signal from terminal 1 (DIN1). The
Manual
mode is normally used for test and programming, as well
as running the inverter, with the use of the keyboard.
The inverter will start the motor automatically when it is powered up if terminal 1 (DIN1 = run signal) is active
and parameter
AutoStart
=
ON
. Parameter
AutoStart
is factory set to OFF
to prevent unintentional motor
starts during commissioning. If the inverter is powered up with an active run signal and
AutoStart
= OFF, the
inverter will remain in mode
Inhibit
until run signal goes inactive (or
AutoStart
is set ON).
The following flowchart Fig. 10 shows how to switch between
Manual
and
Auto
modes:
