Top . The top line of the LCD display shows the basic status
information of the drive .
• Hand – Indicates that the drive control is local, that is,
from the control panel .
• Auto – Indicates that the drive control is remote, such as
the basic I/O (X1) or fieldbus.
• – Indicates the drive and motor rotation status as
follows:
Upper Right – shows the active reference .
Middle . Using parameter group 34 on
of the LCD display can be configured to display:
• One to three parameter values
— The default display shows
parameters 0103 (OUTPUT
FREQ) in percentages,
0104 (CURRENT) in
amperes and 0120 (AI1) in
milliamperes .
— Use parameters 3401, 3408, and 3415 to select the
parameters (from Group 01) to display . Entering
"parameter" 0100 results in no parameter displayed .
For example, if 3401 = 0100 and 3415 = 0100, then
only the parameter specified by 3408 appears in the
Control Panel display .
— You can also scale each parameter in the display, for
example, to convert the motor speed to a display of
conveyor speed . Parameters 3402...3405 scale the
parameter specified by 3401, parameters 3409...3412
scale the parameter specified by 3408, etc.
• A bar meter rather than one of the parameter values .
— Enable bar graph displays using parameters 3404,
3411 and 3418 .
Bottom . The bottom of the LCD display shows:
• Lower Corners – show the functions currently assigned
to the two soft keys .
• Lower Middle – displays the current time (if configured to
show the time) .
