Stop command from serial communication
[OFF/STOP] is used for stopping the connected
motor in Hand or Auto mode. This key can be
diabled in parameter 013. If the stop function is
activated, the main display will flash.
[AUTO START] is used if the VLT is to be controlled
through the control terminals. When a start
signal is active on the control terminals and/or
serial bus, the VLT drive will start.
NB!:
Drive can start at anytime with a start signal
through digital inputs. Digital inputs have
higher priority than control keys [HAND
START] and [AUTO START].
[RESET] is used for manually resetting the drive after
a fault trip (alarm). In this case, the top line of the
display will show TRIP (RESET). If the top line of the
display shows TRIP (AUTO START), the drive will
automatically restart. If the top line of the display
shows TRIPLOCK (DISC. MAINS), input power to the
drive must be removed before the trip can be reset.

Display modes
In Auto operational mode, information is displayed in
any of three programmable displays. Pressing the
[DISPLAY MODE] key enters display mode and toggle
between modes I and II. In Display mode, the [+] and
[-] keys scroll through all data display options. When
in Mode II, holding down the [DISPLAY MODE] key
identifies the units the display is showing on the top
line. Mode IV is available only in local Hand operation.
In normal operation, three data readouts can be
shown on the first (top) line of the display. One readout
is available for line 2 (the large display). Parameters
008, 009 and 010 select the data displayed on the
top line. Parameter 007,
Large Display Readout
,
selects the data displayed on line 2.
The list on the next page defines the operating
data that can be selected for the display readouts.
Line 4 (bottom line) automatically displays the
operating status of the drive.
The active setup number and an arrow indicating
the direction of motor rotation is shown on the right
side of the large display. Clockwise indicates forward
and counterclockwise indicates reverse. The arrow
body is removed if a stop command is given or if
the output frequency falls below 0.01 Hz.
Warnings and alarms (fault trips) will also be displayed.
During an alarm, ALARM and the alarm number
is shown on the large display. An explanation is
given in line 3 or in lines 3 and 4. For a warning,
WARN. and the warning number is shown with an
explanation in line 3 and/or 4. Both alarms and
warnings cause the display to flash.
