■ 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 on page
70.
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 on page 70.
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 on page
70.
Local reference (LOCAL)
If LOCAL has been selected, the reference is set via
the [+/-] keys on the control panel. See also Display
modes on page 71.
Remote reference (REM.)
If REMOTE has been selected, the reference is set via
the control terminals or via serial communication. See
also Display modes on page 71.
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 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 start 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.
