1.0 INTRODUCTION AND PRODUCT DESCRIPTION

1.1 GENERAL INFORMATION

This manual outlines installation and operating practices for the DS9000 series of Digital Speed

Controllers. It also contains a brief description of the product and includes specifications. Before

installing or operating the equipment, read and understand this manual.

1.2 DIGITAL SPEED CONTROLLER

The SECO DS9000 Digital Speed Controller is a closed loop digital speed regulator which can operate

as a Speed Set point controller or as a precision follower when used with an AC or DC drive. The

controller will maintain a long term speed accuracy of ±.01% of top speed and the 16-bit

microcontroller used in the unit provides a 10ms control loop update time, giving tight control and

good stability.

The DS9000 allows up to eight preset speeds and two sets of the following parameters, maximum

speed, minimum speed, acceleration time and deceleration time to be set by the user. Other

parameters such as scaling factors and stabilizing gains are also adjustable. An easy to read digital

readout shows speed in user selected engineering units. When used as a follower, the digital readout

will show the speed of the controlled motor or the speed of the reference.

The DS9000 will allow two complete sets of operator adjustments to be preset. This means the unit

can be set up to handle two different applications or products. Selection of the operating set of

parameters is by terminal strip connection at the rear of the unit.

The 0-10VDC output signal to the AC or DC drive being controlled is isolated from common on the

DS9000 and can be connected to non-isolated motor controllers.

TACH/REF Selects display of either Tach signal or Reference Set-point while

running.

UP Increases speed or data values or scrolls up the Program parameters.

DOWN Decreases speed or data values or scrolls down the Program

parameters.

VALUE/CODE Changes display to either actual value of a parameter or parameter

name (used in Program Mode only)

HI/LOW Allows displayed value to be changed, either one count at a time

(LOW range) or 100 counts at a time (HI range) by the Up or Down

Arrow Key. In the Follower mode, the HI range changes the displayed

value by 10 counts at a time while running to allow for smaller

maximum incremental ratio changes.

LED DISPLAYS:

HI ADJ LED Indicates that HI/LOW key input is in High mode.

LOW ADJ LED Indicates that HI/LOW key input is in Low mode.

TACH LED Indicates that display is actual speed of controlled motor or reference

input.

Indicates Program mode when LED is blinking

REFERENCE LED Indicates that display is the speed set-point.

NOTE: The TACH and REFERENCE LED are only used while the Start input is on.

1.7 REAR PANEL FUNCTIONS

The rear panel of the DS9000 contains 3 terminal strips to which the connections are made and has a

number of DIP switches to allow various parameters to be set for a particular application.

1.7.1 DIP SWITCH POSITIONS

1.8 SYSTEM PARAMETERS, OPERATIONAL, SETUP AND TUNE-UP

The DS9000 allows the user to change or “program” eight Operational parameters in order to adjust

the control to the particular application. Of the additional nine parameters, six are explained in

sections 3.0 and 4.0 and the remaining three in section 5.0.

It is not necessary to go to PROG mode to change the currently selected active speed/ratio. When not

in PROG mode the current value is displayed and it may be changed simply by pushing the UP or

DOWN key.

The Operational parameters that can be changed while operating the unit are:

PS1 Preset Speed #1/ Preset Ratio #1 – Adjustable by UP and DOWN Arrow keys. Value limited by

HI and LOW values. Readout scaling set by SCFO and decimal point position set by SCDO. As

shipped the default value for speed ranges is 0-1800 (RPM).

PS2 Preset Speed #2/ Preset Ratio #2 – Adjustable by UP and DOWN Arrow keys. Value limited by

HI and LOW values. Readout scaling is the same as PS1.

PS3 Preset Speed #3/ Preset Ratio #3 – Adjustable by UP and DOWN Arrow keys. Value limited by

HI and LOW values. Readout scaling is the same as PS1.

PS4 Preset Speed #4/ Preset Ratio #4 – Adjustable by UP and DOWN Arrow keys. This preset

speed is not limited by Max;. Speed (HI) or Minimum Speed (LO) parameters. It can be set to

SCF0 (Max) or 0 (Min). Readout scaling is the same as PS1.

While in PROG mode the currently selected active speed/ratio will be indicated by a “-“ before its

corresponding number, example: “PS-2”. If the status of TB1-4 and 5 are changed while in PROG

Mode, the DS9000 will not recognize the change until you move out of PROG Mode.

Terminal Strip Input Connections

Active

Parameter TB1-4 TB1-5 Group

PS1 OPEN OPEN A

PS2 TB1-12 OPEN A

PS3 OPEN TB1-12 B

PS4 TB1-12 TB1-12 B

TB1-9 and TB1-12 are both signal common and either one can be used as a tie point for signal

common.

Note: Depending on the Group selected, only two Speed or Ratio Parameters can be viewed, either

Group A, PS1 and PS2, or Group B, PS3 and PS4. To view the opposite set, make the

appropriate changes to the connection at TB1-5.

The setup parameters are similar to those that would be set via potentiometers or jumpers on an

analog device. These are set at start up and usually do not need to be changed unless the process to be

performed changes.
