Status messages
Status messages appear in the 4th line of the
display - see example below.
The left part of the status line indicates the active
type of control of the frequency converter.
The centre part of the status line indicates
the active reference.
The last part of the status line gives the present
status, e.g. "Running", "Stop" or "Stand by".

Auto mode (AUTO)
The frequency converter is in Auto mode, i.e. control
is carried out via the control terminals and/or serial
communication. See also
Auto start.
Hand mode (HAND)
The frequency converter is in Hand mode, i.e. control
is carried out via the control keys. See
Hand start
.
OFF (OFF)
OFF/STOP is activated either by means of the control
key, or by the digital inputs
Hand start
and
Auto start
both being a logic "0". See also
OFF/STOP
Local reference (LOCAL)
If LOCAL has been selected, the reference is set via the
[+/-] keys on the control panel. See also
Display modes
.
Remote reference (REM.)
If REMOTE has been selected, the reference is set
via the control terminals or via serial communication.

Display modes
.
Running (RUNNING)
The motor speed now corresponds to the
resulting reference.
Ramp operation (RAMPING)
The output frequency is now changed in accordance
with the preset ramps.
Auto-ramp (AUTO RAMP)
Parameter 208
Automatic ramp-up/down
is enabled,
i.e. the frequency converter is trying to avoid a trip
from overvoltage by increasing its output frequency.
Sleep Boost (SLEEP .BST)
The boost function in parameter 406
Boost
setpoint
is enabled. This function is only possible
in
Closed loop
operation.
Sleep mode (SLEEP)
The energy saving function in parameter 403
Sleep mode timer
is enabled. This means that
at present the motor has stopped, but that it will
restart automatically when required.
Start delay (START DEL)
A start delay time has been programmed i
parameter 111
Start delay
. When the delay
has passed, the output frequency will start by
ramping up to the reference.
Run request (RUN REQ.)
A start command has been given, but the motor
will be stopped until a Run permissive signal
is received via a digital input.
Jogging (JOG)
Jog has been enabled via a digital input or
via serial communication.
Jog request (JOG REQ.)
A JOG command has been given, but the motor
will remain stopped until a
Run permissive
signal
is received via a digital input.
Freeze output (FRZ.OUT.)
Freeze output has been enabled via a digital input.
Freeze output request (FRZ.REQ.)
A freeze output command has been given, but the
motor will remain stopped until a Run permissive
signal is received via a digital input.
Reversing and start (START F/R)
Reversing and start
[2] on terminal 19 (parameter
303
Digital inputs
) and
Start
[1] on terminal 18
(parameter 302
Digital inputs
) are enabled at the
same time. The motor will remain stopped until
one of the signals becomes a logic ‘0
’
