Keys for Local Operation
The following keys are used for local operation:
This key is used for starting up the VLT Series
3500 .
This key is used for local control of the drive
from this control panel. When this key is
depressed, the operating panel display looks
as shown below. This key can be deactivated
through parameter 008 if desired.
When in “Local” mode these keys are used to
increase or decrease the output frequency of
the drive.
STOP
This key is used to stop the connected motor.
If stop is activated, the run relay will drop out
and the top line of the display will start to flash. This key
does not turn off the AC line and therefore cannot be
used as a safety switch. This will stop the drive when it is
in either Local/Hand or Remote/Auto mode. This key can
be deactivated through parameter 007 if desired.
NOTE:
Whether in Local/Hand or Remote/Auto mode,
it is necessary to press the Start key to restart
the drive.
RESET
This key is also used to reset the drive after a
fault trip that is not automatically reset.
Shown below is the appearance of the display when in
local mode and the drive is ready to run.
In the “Local” mode, the second line in the display will
indicate the relative speed. If all squares are filled, it
indicates that the drive is running at the commanded
speed. Hollow squares indicate that a stop command has
been given and there is a speed command or that the
drive is in the process of accelerating to the commanded
speed. If a run command is given, the drive will
accelerate to the commanded speed. A complete row of
dashes indicates that there is no speed command. The
value of the local speed command, in Hz, is shown in the
lower right corner of the display whether the drive is
running or stopped.
This key is used to switch to the Remote/Auto
mode in which the drive is controlled using
external Run/Stop and speed reference
signals.
These keys are used for switching between
local operation and remote operation. When
Remote/Auto is selected REMOTE will be
indicated in the middle of the third row of the
display.
