Page 5: Introduction And Product Description
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. -
Page 6: Front Panel Controls
+5VDC power supply for encoders (max current 40mA) FRONT PANEL CONTROLS The DS9000 Front Panel has a 4-digit LED readout, 6 keypad controls, and 4 LED status indicators. The keypad controls are: PROG – Selects Program Mode, allows adjustment of:... -
Page 7: Rear Panel Functions
NOTE: The TACH and REFERENCE LED are only used while the Start input is on. 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. -

Page 10: System Parameters, Operational, Setup And Tune-Up
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. -
Page 11: Modes Of Operation
In the Set-Point Controller Mode the speed set-point for the controlled motor is entered by the operator on the key pad and displayed on the 4-digit display. The DS9000 compares this set-point with the signal from the feedback pulse generator and provides a control signal to the drive to reduce... -
Page 12: Follower
In the Follower mode the DS9000 will bring the pulses on the output shaft into synchronization with the pulses of the Follower reference thus providing a “position lock” on the two shafts. If the ratio is changed while running the position counters are set to zero and synchronization will restart at that point. -
Page 13: Ds9000 Mounting
To mount the DS9000 in your panel, follow these steps: 1. Cut out the mounting hole for the DS9000 as shown in the panel cutout dimensions in Fig. 2.1. 2. Remove the two socket head screws in the back of the DS9000 with a 1/16” hex wrench. -
Page 14: Air Contaminants
Shielded cable is required for the pulse generator, and all low-level signal circuits to eliminate the possibility of electrical interference. Connect the shield to chassis ground at the controller end of the cable only. There should not be any connections between the DS9000 signal common and any other ground or common. -
Page 15: Wiring The System
Connect the AC or DC drive in accordance with the manufacturer’s instructions. Connections for SECO drives are shown in Figures 2.2 thru 2.8. Connect the DS9000 as shown in Fig 1. Note it is important that the DS9000 Run signal is activated at the same time the drive is started. -
Page 16: Adding The Ds9000
The DS9000 provides a signal that replaces the signal usually obtained from the speed potentiometer on the drive to be controlled. The control signal from the DS9000 is isolated from ground and common on the DS9000 and the signal may be connected to non-isolated drives. -

PROG mode. In addition, go out of the PROG mode before restarting the DS9000. The motor will not restart until you go out of PROG mode. If the tach LED is flashing, PROG mode is active, press the PROG key to move out of PROG mode. - Page 28 Scaling the Motor Speed, Open Loop Control To ensure proper speed scaling of the motor controller and the DS9000, the first step is to operate the system in an “open loop” mode. The DS9000 will provide a 0-10 VDC speed input signal just like a...

“closed-loop” operation. 1. Set Dip SW#2 in the ON position. This sets the DS9000 in the “Open Loop” or manual mode of operation. If you have not removed the speed pot from the drive that you used to start the drive in Section 2.5, do so now. -
Page 30: Rpm Programming/Readout
RPM PROGRAMMING/READOUT As shipped from the factory, the DS9000 is set up to accept a selected speed as RPM, and to display motor speed in tach mode as RPM when used with a 60 pulse/revolution pulse generator. In this case, no adjustments or calibrations are necessary. -

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”. -
Page 32: Operating The Ds9000 As A Follower Controller
Follower Motor will run at an exact ratio, programmable from 0.001 to 9.999, to the speed of a master motor or digital reference signal. For a typical wiring diagram for the DS9000 connected as a Master and a Follower Controller, refer to Fig. 4.1. -

(Maximum RPM) (Pulses per revolution) (1 min. ) = Max. Freq. (Hz) (60 sec.) Example 1 (1800 RPM) (60 PPR) (1 min.) = 1800 Hz (60 sec.) Example 2 (1500 RPM) (120 PPR) (1 min.) = 3000 Hz (60 sec.) Now that you know the maximum frequency of the input, calculate the requirements for the follower system.

Page 36: Starting And Stopping
The DS9000 may be wired into the Start/Stop circuit of the motor controller or use the internal DS9000 +5VDC supply. To start the DS9000, a DC voltage of between 5 and 25 volts DC must be applied to terminals TB1-1 and TB1-2. Generally this can be obtained from the DC drive’s Start/Stop Logic Power Supply. -
Page 37: Setting Your Ratio
Section 1.8 for the procedures to select the desired ratio parameter. With the start input preset, DS9000 operational, pressing the UP or DOWN key in HI mode changes the value of PS1, PS2, PS3 or PS4, by units of 10 and by units of 1 in LO mode. -
Page 38: Tuning Your System
3.0 for information on these parameters. TUNING YOUR SYSTEM The DS9000 utilizes a digital version of a classic proportional and integral (PI) error amplifier with reference feed forward. An error signal is generated by comparing the speed reference entered by the operator to the actual speed of the controlled motor, measured by the pulse generator. -
Page 39: Applications Using Two Or More Ds9000 Units
PARALLEL CONNECTION In a parallel system, one DS9000 is used in master mode to control a motor. Two or more DS9000’s programmed for follower mode may be connected to the pulse generator of the master unit’s controlled motor. -
Page 40: Troubleshooting Tips
Contact closure input changes to the DS9000 will not be recognized when in PROG mode. When you move out of PROG mode, the DS9000 will update the status of the inputs. The parameter data tables, A or B, can only be changed in the stopped state, (no Start input). -
Page 41: Master Follower Operation
If the setpoint (PS1 for example) is at 900 and SCF0 is set to 1800 then there would be – 5V out of the DS9000 and the drive should be going ½ speed. If the drive has an offset control then it can be set to half speed with this setting. - Page 42 PARAMETER CODE/VALUE WORKSHEET PARAMETER CODE MASTER FOLLOWER DEFAULT DATA TABLE “A” DATA TABLE “B” _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________ _______________ 1800 _______________ _______________ ACE1 _______________ _______________ dEC1 _______________ _______________ FEd0 FEd0 _______________ _______________ SCF0 SCF0 1800 _______________ _______________ SCd0...
