KEYPAD PROGRAMMING
The keypad is mounted integrally with the DMR. It is
connected to the main DMR through a ribbon cable and
is used for viewing and modifying various parameters
within the systems. The module consists of the
following: a 20-button keypad; two independent sets of
8-digit, 7-segment LED displays; and a row of 8
individual status LEDs. The keypad is illustrated in
Figure 2-1.
Each of the 8-digit LED displays is arranged in two
separate fields: a 2-digit parameter number, followed by
a 6-digit parameter value. Different parameters in the
system may be viewed by entering their particular code
number into the first field. The current value of that
parameter will automatically be displayed in the second
field, the parameter value field. Any two parameters
may be viewed simultaneously on the display panel.
A keypad lock/unlock feature has been added to make
data entry easier and more versatile. Parameters that
had previously been set and locked in at the factory will
now be programmed in the field. All parameters are
protected from inadvertent change except running
speeds, angles, Inch and Micro Inch speeds. These are
parameters 30 thru 41, 45 and 46. To change any of the
protected parameters, unlock the key pad by pressing
the following keys in the order listed within five seconds
of one another: F1, F2, ENTER. Use the up or down
arrow until the word “UNLOCK” is displayed on the
DMR. You will have fifteen minutes to change any of the
protected parameters. At the end of this timed interval,
the DMR will automatically return to the locked
configuration. (The LOCK/UNLOCK feature may be
disabled by selecting DSBL).
Some parameters must be set up before the press will
function properly. These should be set at the initial start-
up of the control/press. Some of these are as follows:
42 Stop-on-top creep speed angle
43 Stop-on-top apply brake angle
44 Creed speed-top
45 Micro inch speed
46 Inch speed
81 Stop-on-bottom creep speed angle
82 Stop-on-bottom apply brake angle
83 Creep speed-bottom
Certain parameter are unique to each press as the
mechanical requirements change from one unit to
another. The table below lists the set parameters and
must be programmed to insure proper press operation.
26 Maximum speed
27 Line voltage
28 Clutch current
29 Brake current
72 No. of speed feedback periods averaged
73 Baud rate
78 Gear box ratio
79 Tach pulses per revolution
80 Pot selector
Parameters are selected for viewing by first selecting
either the top or bottom display window (called the active
display), and then entering the 2-digit code for that
parameter in the parameter number field. The top
display windows are selected by pressing the Top button
on the keypad, and similarly the bottom display windows
are selected by pressing the Bot key. When the display
windows become active, the two decimal point LEDs in
the parameter number field will light, indicating that it is
the active display. The opposite set of display windows
will then become inactive (decimal points off) and will
continue to display the value of the last parameter
number that was entered. Thus, by selecting the top
display and entering one code number, and then
selecting the bottom display and entering a different
code number, it is possible to obtain a continuous
readout of any two parameters in the system.
Parameters that may be displayed are broken down into
two, categories, non-alterable parameters; and operator-
alterable parameters. Non-alterable parameters are for
display only and cannot be modified by the operator.
Operator-alterable parameters are variables that are
accessible for modification in order to set-up and adjust
the system performance. Refer to CES Controller
Parameters on the previous page for an explanation of
which parameter numbers are for display only and which
ones are operator-alterable. All parameters are listed in
Table 3-3 and 3-4.
In order to modify an operator-alterable parameter, the
code for that particular parameter must be entered into
the parameter number field of the active display, which
will then display its current value in the parameter value
field.
Pressing the Up arrow (↑) button on the keypad will
increment that parameter value by one unit for each
keystroke. Similarly, pressing the Down arrow button (↓)
will decrement the value by one unit per keystroke.
Pressing and holding the Up or Down arrow button (↑↓)
down for longer than one second will invoke a keystroke
auto-repeat function, which will continue to increment or
decrement the parameter value for as long as the button
is held down. The auto-repeat rate of the button is
controlled by the display panel update time parameter
and can thus vary from 0.1 to 0.5 second per stroke.
In order to allow for more rapid parameter changes, a
fast up/down function is available, which will alter the
value by 10 units per increment. This is obtained by first
pressing the Asterisk button (*) and then either the Up
arrow (↑) or the Down arrow button to increment or
decrement the parameter by 10 units per keystroke.
