NOTE: The current parameter value appears below the
highlighted parameter.
To view the default parameter value, press the UP/
DOWN buttons simultaneously.
The most typical and necessary parameters to
change are parameter groups 99 Start-up data, 10
Start/Stop/Dir, 11 Reference Select, 20 Limits, 21
Start/Stop, 22 Accel/Decel, 30 Fault Functions and
98 & 53 Groups for Comms.
To restore the default factory settings, select the
application macro HVAC default.
Modes
The MD4 HVAC control panel has several different modes for
conguring, operating and diagnosing the drive. The modes are:
• Standard display mode – Shows drive status information
and operates the drive.
• Parameters mode – Edits parameter values individually.
• Changed parameters mode – Shows changed
parameters.
• Fault logger mode – Shows the drive fault history.
• Drive parameter backup mode – Stores or uploads the
parameters.
• Clock set mode – Sets the time and date for the drive.
• Alarm mode – Reporting mode triggered by drive alarms.
Standard Display Mode
Use the standard display mode to read information on the
drive’s status and to operate the drive. To reach the standard
display mode, press EXIT until the LCD display shows status
information as described below.
Status Information
Table 1: Status Information
Control Panel Display Signicance
Rotating arrow (clockwise or
counterclockwise)
• Drive is running and at setpoint
• Shaft direction is forward or reverse
Rotating dotted arrow blinking Drive is running but not at setpoint
Stationary dotted arrow
Start command is present, but motor
is not running. E.g. start enable is
missing.
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 eldbus.
• – Indicates the drive and motor rotation status as
follows:
Upper Right – shows the active reference.
Middle. Using parameter group 34 on page 57, the middle
of the LCD display can be congured 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 specied 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 specied by 3401, parameters 3409…3412
scale the parameter specied 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 congured to
show the time).
