HOW TO SET SPEED
Once the units of speed have been selected, setting speed is accomplished by using the UP or DOWN
keys to adjust the numerical value displayed. If the TACH LED is flashing, the DS9000 is in the
program mode, and PROG Key should be pressed to leave the program mode. To adjust speed in fine
increments, press the HI/LOW key until the LO LED is illuminated. Each time the UP or DOWN keys
are pressed, a change of one unit will occur. Holding down either key will result in a continuous
increase or decrease. To quickly change speed in larger increments, press the HI/LOW key until the
HI LED illuminates. Each time the UP or DOWN keys are pressed, a change of 100 units will occur.
In REF mode (REF LED illuminated), the display shows the speed that has been set by the operator.
In TACH mode (TACH LED illuminated) the display shows actual motor speed. Select REF or TACH
mode by pressing the TACH/REF key.

HOW TO CHANGE PARAMETERS
The DS9000 is made flexible and application friendly by a series of seventeen parameters which may
be checked or changed from the keypad. Depending on the security mode and whether the DS9000 is
running or stopped, certain parameters may or may not be accessed or changed. When the security
mode is on, only the four Set Point or Ratio Parameters, PS1, PS2, PS3 and PS4 may be changed.
3.5.1
SECURITY, INHIBITING PARAMETER CHANGES
By connecting TB1-6 to circuit common (TB1-9 or TB1-12), the DS9000 security mode is activated. In
this mode, the only parameters that the operator can change from the keypad are the speed setpoint
(or ratio presets) PS1, PS2, PS3 and PS4. With TB1-6 open (no connection) the value of active preset
may be changed simply by pressing the UP or DOWN keys. Its value may be displayed by pressing the
"TACH/REF" key until the "REF" LED is illuminated. By varying the connections (switches or
contacts) to TB1-4 and 5, the user can select PS1, PS2, PS3 or PS4 and display or change these
parameters in similar fashion. All other parameters are locked out when the security mode is active.
3.5.2
PARAMETER CHANGES WITH DS9000 OFF (STOPPED)
When the DS9000 is in STOP mode, that is, when the START signal is off, and the security mode is
not selected, all parameters may be checked and changed by the operator from the keypad. To check a
parameter, enter PROG mode by pressing "PROG". The "TACH" LED will begin to blink, indicating
that the DS9000 is in PROG mode. While in this mode, the DS9000 should not be started as the
motor will not run until you move out of PROG mode. Pressing the UP or DOWN keys will scroll
through the parameters by code name. When the parameter to be changed is reached, press the
"VALUE/CODE" key. The display will now indicate the VALUE of the selected parameter. To change
it, press either the UP or DOWN keys. When finished, press "PROG" to return to normal display.
3.5.3
PARAMETER CHANGES WITH DS9000 RUNNING
When the DS9000 is running, or the START signal is on and security is off, only the eight basic
operator adjustment parameters may be accessed. These are checked and changed in the same way as
described in section 3.5.2.
As stated in Section 2.7.3, improper system operation may occur if you move into PROG mode (Tach
LED will flash) while operating your system. The contact inputs to TB1 will not be recognized until
you move out of PROG mode. For safe operation, follow 3.5.2 to interrogate or change parameter
values.
3.6
CHANGING PARAMETER DATA TABLES (A & B)
A unique feature of the DS9000 is its ability to store and use two complete sets of user adjustments.
These are called Parameter Data Tables A and B. This feature can be useful when, for example, two
different processes must be run, each having its own set of parameters.
Parameter Data Table A is selected when TB1-3 is Open (no connection) and data table B when TB1-3
is connected to circuit common (TB1-9 or 12). This connection may only be changed while the
START input is OFF and not in PROG mode.
