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 VLT 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 VLT 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 VLT frequency converter is in Hand
mode, i.e. control is carried out via the control
keys. See also
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 mode
s.
Remote reference (REM.)
If REMOTE has been selected, the reference
is set via the control terminals or via serial
communication. See also

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-down
is
enabled, i.e. the VLT 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.
